18.5.2
FLMCR2 is an 8-bit register that monitors the presence or absence of flash memory program/erase
protection (error protection). FLMCR2 is initialized to H'00 by a reset, and in hardware standby
mode.
When on-chip flash memory is disabled, a read will return H'00.
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.
Bits 6 to 0—Reserved: These bits are always read as 0.
