17.7.2
FLMCR2 is an 8-bit register that monitors the presence or absence of flash memory program/erase
protection (error protection) and performs setup for flash memory program/erase mode. FLMCR2
is initialized to H'00 by a reset, and in hardware standby mode. The ESU and PSU bits are cleared
to 0 in software standby mode, hardware protect mode, and software protect mode.
When on-chip flash memory is disabled, a read will return H'00.
