Section 19 ROM (256 kB Version)
19.5.4
EBR2 is an 8-bit register that specifies the flash memory erase area block by block. EBR2 is
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 EBR2 is set to 1, the corresponding block can be erased. Other
blocks are erase-protected. Only one of the bits of EBR1 and EBR2 combined can be set. Do not
set more than one bit. 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 19.3.
