19.2.3
EBR2 is an 8-bit register that designates small flash-memory blocks for programming and erasure.
EBR2 is initialized to H'00 by a reset, in the standby modes, and when 12 V is not applied to FV
pin. When a bit in EBR2 is set to 1, the corresponding block is selected and can be programmed
and erased. Figure 19.2 and table 19.6 show a block map.
Note: * The initial value is H'00 in modes 2 and 3 (on-chip ROM enabled). In mode 1 (on-chip ROM
Bits 7 to 0—Small Block 7 to 0 (SB7 to SB0): These bits select small blocks (SB7 to SB0) to be
