ESU, EV, PV, or E bit at the same time.
22.5.2
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, subactive mode, subsleep mode, and watch mode.
When on-chip flash memory is disabled, a read will return H'00 and writes are invalid.
Bit 7—Flash Memory Error (FLER): Indicates that an error has occurred during an operation on
flash memory (programming or erasing). When FLER is set to 1, flash memory goes to the error-
protection state.
