Section 6 ROM
6.5.3
EBR2 is an 8-bit register that specifies small flash-memory blocks for programming or erasure.
EBR2 is initialized to H'00 upon reset, in sleep mode, subsleep mode, watch mode, and standby
mode, and when 12 V is not applied to FV
block is selected and can be programmed and erased. The erase block map is shown in figure 6.7,
and the correspondence between bits and erase blocks is shown in table 6.8.
Note:
Bits 7 to 0 Small Block 7 to 0 (SB7 to SB0): These bits select small blocks (SB7 to SB0) to be
programmed and erased.
