FLMCR2 is an 8-bit register that controls the flash memory operating modes. FLMCR2 is
initialized to H'00 by a reset, and in hardware standby mode and software standby mode.
When on-chip flash memory is disabled, a read will return H'00 and writes are invalid.
Bit 7âFlash 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.
