The flash memory control register (FLMCR) is an eight-bit register that controls the flash memory
operating modes. 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 by a reset, in
the standby modes, and when 12 V is not applied to V
entry to a standby mode initializes FLMCR to H'80.
