address_offset : 0x0 Bytes (0x0)
size : 0xC byte (0x0)
mem_usage : registers
protection :
NMI mask for IRQs 0 through 31. This register is core-local, and is reset by a processor warm reset.
address_offset : 0x0 Bytes (0x0)
size : 32 bit
access : read-write
reset_value : 0x0
reset_Mask : 0x0
NMI_MASK0 :
bits : 0 - 31 (32 bit)
access : read-write
NMI mask for IRQs 0 though 51. This register is core-local, and is reset by a processor warm reset.
address_offset : 0x4 Bytes (0x0)
size : 32 bit
access : read-write
reset_value : 0x0
reset_Mask : 0x0
NMI_MASK1 :
bits : 0 - 19 (20 bit)
access : read-write
Nonstandard sleep control register
address_offset : 0x8 Bytes (0x0)
size : 32 bit
access : read-write
reset_value : 0x0
reset_Mask : 0x0
LIGHT_SLEEP : By default, any processor sleep will deassert the system-level clock request. Reenabling the clocks incurs 5 cycles of additional latency on wakeup.
Setting LIGHT_SLEEP to 1 keeps the clock request asserted during a normal sleep (Arm SCR.SLEEPDEEP = 0), for faster wakeup. Processor deep sleep (Arm SCR.SLEEPDEEP = 1) is not affected, and will always deassert the system-level clock request.
bits : 0 - 0 (1 bit)
access : read-write
WICENREQ : Request that the next processor deep sleep is a WIC sleep. After setting this bit, before sleeping, poll WICENACK to ensure the processor interrupt controller has acknowledged the change.
bits : 1 - 1 (1 bit)
access : read-write
WICENACK : Status signal from the processor's interrupt controller. Changes to WICENREQ are eventually reflected in WICENACK.
bits : 2 - 2 (1 bit)
access : read-only
