NOTE:
NOTE:
Note: LVI5OR3 bit is only reset via POR (power-on reset)
Address:
Address:
To ensure correct operation of the MCU under all operating conditions,
the user must write data $1C to address $0033 immediately after reset.
This is to ensure proper termination of an unused module within the
MCU.
On a FLASH device, the options except LVI5OR3 are one-time writeable
by the user after each reset. The LVI5OR3 bit is one-time writeable by
the user only after each POR (power-on reset). The CONFIG registers
are not in the FLASH memory but are special registers containing one-
time writeable latches after each reset. Upon a reset, the CONFIG
registers default to predetermined settings as shown in
