Write 0x3E77 to unlock this register and allow other bits to be changed. NOTE: This register must be
unlocked on a write-by-write basis, so the UNLOCK bitfield must contain the correct key value during
all writes to this register in order to update any other bitfield values in the register.
0x3E77
Reserved.
Set this bit to 1'b1 to disable the chip shutting down by a fast falling edge of PSWITCH. Setting this
bit will be useful for preventing fast falling edges on the PSWITCH pin from resetting the chip. It may
also be useful increasing system tolerance of noisy EMI environments.
Optional bit to disable all paths to power off the chip except the watchdog timer. Setting this bit will be
useful for preventing fast falling edges on the PSWITCH pin from resetting the chip. It may also be
useful increasing system tolerance of noisy EMI environments.
Powers down the chip.
