FLMCR is an 8-bit register used for flash memory operating mode control. Transitions to program
mode, erase mode, program-verify mode, and erase-verify mode are made by setting bits in this
register. FLMCR is initialized to H'00 upon reset, in sleep mode, subsleep mode, watch mode, and
standby mode, and when 12 V is not applied to FV
initializes FLMCR to H'80.
