FLMCR2 monitors the state of flash memory programming/erasing protection (error protection)
and sets up the flash memory to transit to programming/erasing mode. FLMCR2 is initialized to
H'00 by a reset or in hardware standby mode. The ESU and PSU bits are cleared to 0 in software
standby mode, sub-active mode, sub-sleep mode, or watch mode, or when the SWE bit in
FLMCR1 is cleared to 0.

Erase Setup
When this bit is set to 1 while SWE = 1, the flash
memory transits to the erase setup state. When it
is cleared to 0, the erase setup state is cancelled.
Set this bit to 1 before setting the E bit in
FLMCR1 to 1.
Program Setup
When this bit is set to 1 while SWE = 1, the flash
memory transits to the program setup state.
When it is cleared to 0, the program setup state is
cancelled. Set this bit to 1 before setting the P bit
in FLMCR1 to 1.
