ISPEN : ISP Enable Bit (Write Protected) ISP function enable bit. Set this bit to enable ISP function.
bits : 0 - 0 (1 bit)
access : read-write

Enumeration:

End of enumeration elements list.

ISPFF : ISP Fail Flag (Write Protected) This bit is set by hardware when a triggered ISP meets any of the following conditions: (1) Destination address is illegal, such as over an available range. (2) Invalid ISP commands. (3) Program command at the address which is already programmed. Note 1: This bit is write protected. Refer to the SYS_REGLCTL register. Note 2: This bit needs to be cleared by writing 1 to it.
bits : 6 - 6 (1 bit)
access : read-write

ISPGO : ISP Start Trigger (Write Protected) Write 1 to start ISP operation and this bit will be cleared to 0 by hardware automatically when ISP operation is finished. Note: This bit is write protected. Refer to the SYS_REGLCTL register.
bits : 0 - 0 (1 bit)
access : read-write

Enumeration:

End of enumeration elements list.

ISPADDR : ISP Address ISPADDR[1:0] must be kept 00 for ISP 32-bit operation. For CRC32 Checksum Calculation command, this field is the OTP starting address for checksum calculation, 32 bytes alignment is necessary for CRC32 checksum calculation. For 32-bit Program, ISP address needs word alignment (4-byte).
bits : 0 - 31 (32 bit)
access : read-write

ISPBUSY : ISP Busy Flag (Read Only) This bit is the mirror of ISPGO (OMC_ISPTRG[0]).
bits : 0 - 0 (1 bit)
access : read-only

Enumeration:

End of enumeration elements list.

ISPFF : ISP Fail Flag (Read Only) This bit is the mirror of ISPFF(OMC_ISPCTL[6]), it needs to be cleared by writing 1 to OMC_ISPCTL[6]. This bit is set by hardware when a triggered ISP meets any of the following conditions: (1) Destination address is illegal, such as over an available range. (2) Invalid ISP commands. (3) Program command at the address which is already programmed.
bits : 6 - 6 (1 bit)
access : read-only

VECMAP : Vector Page Mapping Address (Read Only) The current flash address space 0x0000_0000~0x0000_01FF is mapping to address {VECMAP[20:0], 9'h000} ~ {VECMAP[20:0], 9'h1FF}
bits : 9 - 29 (21 bit)
access : read-only

ISPDAT : ISP Data Write data to this register before ISP program operation. Read data from this register after ISP read operation.
bits : 0 - 31 (32 bit)
access : read-write

CMD : ISP Command ISP command table is shown below: The other commands are invalid. Note: The supply voltage of VDD must be higher than 2.5V for OTP programming.
bits : 0 - 6 (7 bit)
access : read-write
