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 power-on reset, and in hardware standby mode and software standby mode.

When on-chip flash memory is disabled, a read will return H'00.
