18.5.2 Flash Memory Control Register 2 (FLMCR2)
FLMCR2 monitors the state of flash memory programming/erasing protection (error protection)
and sets up the flash memory to transit to programming/erasing mode. FLMCR2 is initialized to
H'00 by a reset or in hardware standby mode. The ESU and PSU bits are cleared to 0 in software
standby mode, sub-active mode, sub-sleep mode, or watch mode, or when the SWE bit in
FLMCR1 is cleared to 0.
