Bits 15:0 of public device ID. (ECC)
The CHIPID0..3 rows contain a 64-bit random identifier for this chip, which can be read from the USB bootloader PICOBOOT interface or from the get_sys_info ROM API.
The number of random bits makes the occurrence of twins exceedingly unlikely: for example, a fleet of a hundred million devices has a 99.97% probability of no twinned IDs. This is estimated to be lower than the occurrence of process errors in the assignment of sequential random IDs, and for practical purposes CHIPID may be treated as unique.

Bits 15:0 of private per-device random number (ECC)
The RANDID0..7 rows form a 128-bit random number generated during device test.
This ID is not exposed through the USB PICOBOOT GET_INFO command or the ROM `get_sys_info()` API. However note that the USB PICOBOOT OTP access point can read the entirety of page 0, so this value is not meaningfully private unless the USB PICOBOOT interface is disabled via the DISABLE_BOOTSEL_USB_PICOBOOT_IFC flag in BOOT_FLAGS0.

Ensure that BOOTSEL_XOSC_CFG and BOOTSEL_PLL_CFG are correctly programmed before setting this bit.
If this bit is set, user software may use the contents of BOOTSEL_PLL_CFG to calculated the expected XOSC frequency based on the fixed USB boot frequency of 48 MHz.
bits : 2 - 2 (1 bit)
access : read-only
FLASH_IO_VOLTAGE_1V8 : If 1, configure the QSPI pads for 1.8 V operation when accessing flash for the first time from the bootrom, using the VOLTAGE_SELECT register for the QSPI pads bank. This slightly improves the input timing of the pads at low voltages, but does not affect their output characteristics.
If 0, leave VOLTAGE_SELECT in its reset state (suitable for operation at and above 2.5 V)

access : read-only
ENABLE_OTP_BOOT : Enable OTP boot. A number of OTP rows specified by OTPBOOT_LEN will be loaded, starting from OTPBOOT_SRC, into the SRAM location specified by OTPBOOT_DST1 and OTPBOOT_DST0.
The loaded program image is stored with ECC, 16 bits per row, and must contain a valid IMAGE_DEF. Do not set this bit without first programming an image into OTP and configuring OTPBOOT_LEN, OTPBOOT_SRC, OTPBOOT_DST0 and OTPBOOT_DST1.
Note that OTPBOOT_LEN and OTPBOOT_SRC must be even numbers of OTP rows. Equivalently, the image must be a multiple of 32 bits in size, and must start at a 32-bit-aligned address in the ECC read data address window.

size : 32 bit
access : read-write
reset_value : 0x0

KEY_VALID : Mark each of the possible boot keys as valid. The bootrom will check signatures against all valid boot keys, and ignore invalid boot keys.
Each bit in this field corresponds to one of the four 256-bit boot key hashes that may be stored in page 2 of the OTP.
A KEY_VALID bit is ignored if the corresponding KEY_INVALID bit is set. Boot keys are considered valid only when KEY_VALID is set and KEY_INVALID is clear.
Do not mark a boot key as KEY_VALID if it does not contain a valid SHA-256 hash of your secp256k1 public key. Verify keys after programming, before setting the KEY_VALID bits -- a boot key with uncorrectable ECC faults will render your device unbootable if secure boot is enabled.
Do not enable secure boot without first installing a valid key. This will render your device unbootable.
bits : 0 - 3 (4 bit)
access : read-only
KEY_INVALID : Mark a boot key as invalid, or prevent it from ever becoming valid. The bootrom will ignore any boot key marked as invalid during secure boot signature checks.
Each bit in this field corresponds to one of the four 256-bit boot key hashes that may be stored in page 2 of the OTP.
When provisioning boot keys, it's recommended to mark any boot key slots you don't intend to use as KEY_INVALID, so that spurious keys can not be installed at a later time.
bits : 8 - 11 (4 bit)
access : read-only
DOUBLE_TAP_DELAY : Adjust how long to wait for a second reset when double tap BOOTSEL mode is enabled via DOUBLE_TAP. The minimum is 50 milliseconds, and each unit of this field adds an additional 50 milliseconds.
For example, settings this field to its maximum value of 7 will cause the chip to wait for 400 milliseconds at boot to check for a second reset which requests entry to BOOTSEL mode.
200 milliseconds (DOUBLE_TAP_DELAY=3) is a good intermediate value.
bits : 16 - 18 (3 bit)
access : read-only
DOUBLE_TAP : Enable entering BOOTSEL mode via double-tap of the RUN/RSTn pin. Adds a significant delay to boot time, as configured by DOUBLE_TAP_DELAY.
This functions by waiting at startup (i.e. following a reset) to see if a second reset is applied soon afterward. The second reset is detected by the bootrom with help of the POWMAN_CHIP_RESET_DOUBLE_TAP flag, which is not reset by the external reset pin, and the bootrom enters BOOTSEL mode (NSBOOT) to await further instruction over USB or UART.

CS1_GPIO : Indicate a GPIO number to be used for the secondary flash chip select (CS1), which selects the external QSPI device mapped at system addresses 0x11000000 through 0x11ffffff. There is no such configuration for CS0, as the primary chip select has a dedicated pin.
On RP2350 the permissible GPIO numbers are 0, 8, 19 and 47.
Ignored if CS1_size is zero. If CS1_SIZE is nonzero, the bootrom will automatically configure this GPIO as a second chip select upon entering the flash boot path, or entering any other path that may use the QSPI flash interface, such as BOOTSEL mode (nsboot).
bits : 0 - 5 (6 bit)
access : read-only
D8H_ERASE_SUPPORTED : If true, all attached devices are assumed to support (or ignore, in the case of PSRAM) a block erase command with a command prefix of D8h, an erase size of 64 kiB, and a 24-bit address. Almost all 25-series flash devices support this command.
If set, the bootrom will use the D8h erase command where it is able, to accelerate bulk erase operations. This makes flash programming faster.
When BOOT_FLAGS0_FLASH_DEVINFO_ENABLE is not set, this field defaults to false.
bits : 7 - 7 (1 bit)
access : read-only
CS0_SIZE : The size of the flash/PSRAM device on chip select 0 (addressable at 0x10000000 through 0x10ffffff).
A value of zero is decoded as a size of zero (no device). Nonzero values are decoded as 4kiB << CS0_SIZE. For example, four megabytes is encoded with a CS0_SIZE value of 10, and 16 megabytes is encoded with a CS0_SIZE value of 12.
When BOOT_FLAGS0_FLASH_DEVINFO_ENABLE is not set, a default of 12 (16 MiB) is used.

Optional PLL configuration for BOOTSEL mode. (ECC)
This should be configured to produce an exact 48 MHz based on the crystal oscillator frequency. User mode software may also use this value to calculate the expected crystal frequency based on an assumed 48 MHz PLL output.
If no configuration is given, the crystal is assumed to be 12 MHz.
The PLL frequency can be calculated as:
PLL out = (XOSC frequency / (REFDIV+1)) x FBDIV / (POSTDIV1 x POSTDIV2)
Conversely the crystal frequency can be calculated as:
XOSC frequency = 48 MHz x (REFDIV+1) x (POSTDIV1 x POSTDIV2) / FBDIV
(Note the +1 on REFDIV is because the value stored in this OTP location is the actual divisor value minus one.)
Used if and only if ENABLE_BOOTSEL_NON_DEFAULT_PLL_XOSC_CFG is set in BOOT_FLAGS0. That bit should be set only after this row and BOOTSEL_XOSC_CFG are both correctly programmed.

The entries are either _VALUEs where the 16 bit value is used as is, or _STRDEFs which acts as a pointers to a string value.
The value stored in a _STRDEF is two separate bytes: The low seven bits of the first (LSB) byte indicates the number of characters in the string, and the top bit of the first (LSB) byte if set to indicate that each character in the string is two bytes (Unicode) versus one byte if unset. The second (MSB) byte represents the location of the string data, and is encoded as the number of rows from this USB_WHITE_LABEL_ADDR i.e. the row of the start of the string is USB_WHITE_LABEL_ADDR value + msb_byte.
In each case, the corresponding valid bit enables replacing the default value for the corresponding item provided by the boot rom.
Note that Unicode _STRDEFs are only supported for USB_DEVICE_PRODUCT_STRDEF, USB_DEVICE_SERIAL_NUMBER_STRDEF and USB_DEVICE_MANUFACTURER_STRDEF. Unicode values will be ignored if specified for other fields, and non-unicode values for these three items will be converted to Unicode characters by setting the upper 8 bits to zero.
Note that if the USB_WHITE_LABEL structure or the corresponding strings are not readable by BOOTSEL mode based on OTP permissions, or if alignment requirements are not met, then the corresponding default values are used.
The index values indicate where each field is located (row USB_WHITE_LABEL_ADDR value + index):

OTP start row for the OTP boot image. (ECC)
If OTP boot is enabled, the bootrom will load from this location into SRAM and then directly enter the loaded image. Note that the image must be signed if SECURE_BOOT_ENABLE is set. The image itself is assumed to be ECC-protected.
This must be an even number. Equivalently, the OTP boot image must start at a word-aligned location in the ECC read data address window.

bits : 0 - 1 (2 bit)
access : read-only
Enumeration:
0 : read_write
Page is fully accessible by Secure software.
1 : read_only
