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.

Flash memory error
Indicates that an error has occurred during flash
memory programming/erasing. When this bit is set to 1,
flash memory goes to the error-protection state.

The initial values should not be modified.
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.
