19.7.3
EBR1 and EBR2 are registers that specify the flash memory erase area block by block; bits 1 and 2 in EBR1 and bits 7 to
0 in EBR2 are readable/writable bits. EBR1 and EBR2 are each initialized to H'00 by a reset, in hardware standby mode
and software standby mode, when a low level is input to the FWE pin, and when a high level is input to the FWE pin and
the SWE bit in FLMCR1 is not set. When a bit in EBR1 or EBR2 is set, the corresponding block can be erased. Other
blocks are erase-protected. Set only one bit in EBR1 or EBR2 (more than one bit cannot be set). When on-chip flash
memory is disabled, a read will return H'00, and writes are invalid.
The flash memory block configuration is shown in table 19-12.
