Section 17 ROM
17.7.3
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 cleared to 0. When a bit in EBR1 or EBR2 is set, the corresponding block can be erased. Other
blocks are erase-protected. Blocks are erased separately (in one-block units), so set only one bit in
EBR1 or EBR2 (more than one bit cannot be set to 1). To erase all blocks, erase one block at a
time, once after another in sequence. Then on-chip flash memory is disabled (modes 4 and 5), a
read with return H'00, and writes are disabled.
The flash memory block configuration is shown in table 17.12.
