The register is used for the Power-On-Reset enable control.
When power on, the POR circuit generates a reset signal to reset the whole chip function,
but noise on the power may cause the POR active again. If set the POR_DIS_CODE
equal to 0x5AA5, the POR reset function will be disabled and the POR function will re-
active till the power voltage is lower to set the POR_DIS_CODE to another value or reset
by chip other reset function. Include:
/RESET, Watch dog, LVR reset BOD reset, ICE reset command and the software-chip
reset function
This bit is the protected bit. It means programming this needs to write “59h”, “16h”, “88h”
to address 0x5000_0100 to disable register protection. Reference the register
REGWRPROT at address GCR_BA+0x100.
