24.5.2
Flash Memory Control Register 2 (FLMCR2)
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.

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.

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.
24.5.3
Erase Block Registers 1 and 2 (EBR1, EBR2)
EBR1 and EBR2 are used to specify the flash memory erase block. EBR1 and EBR2 are
initialized to H'00 by a reset, or in hardware standby mode, software standby mode, sub-active
mode, or sub-sleep mode, or when the SWE bit in FLMCR1 is cleared to 0. Set only one bit to 1 at
a time, otherwise all bits in EBR1 and EBR2 are automatically cleared to 0.
