Note: FLMCR2 is a read-only register, and should not be written to.
FLMCR2 is an 8-bit register used for flash memory operating mode control. 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.
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 always read 0.
