19.3.3
Erase block register 2 (EBR2) is an eight-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, when
12 V is applied to V
EBR2 is set to 1, the corresponding block is selected and can be programmed and erased. Figure
19.2 shows a block map.
Note: * The initial value is H'00 in modes 5, 6, and 7 (on-chip flash memory enabled). In modes 1,
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.
