EBR1 is an 8-bit register that specifies the flash memory erase area block by block. EBR1 is
initialized to H'00 by a reset, in hardware standby mode and software standby mode, and the
SWE1 bit in FLMCR1 is not set. When a bit in EBR1 is set, the corresponding block can be
erased. Other blocks are erase-protected. Set only one bit in EBR1 and EBR2 together (setting
more than one bit will automatically clear all EBR1 and EBR2 bits to 0). 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 17-28.
