6.6.3
EBR specifies the flash memory erase area block. EBR is initialized to H'00 when the SWE bit in
FLMCR1 is 0. Do not set more than one bit at a time, as this will cause all the bits in EBR to be
automatically cleared to 0. When each bit is set to 1 in EBR, the corresponding block can be
erased. Other blocks change to the erase-protection state. See table 6.6 for the method of dividing
blocks of the flash memory. When the whole bits are to be erased, erase them in turn in unit of a
block.

FLPWCR enables or disables a transition to the flash memory power-down mode when the LSI
switches to subactive mode. The power supply circuit can be read in the subactive mode, although
it is partly halted in the power-down mode.
