6.5.2
EBR1 is an 8-bit register that specifies large flash-memory blocks for programming or erasure.
EBR1 is initialized to H'F0 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 4 Reserved: Bits 7 to 4 are reserved; they are always read as 1, and cannot be
modified.
Bits 3 to 0 Large Block 3 to 0 (LB3 to LB0): These bits select large blocks (LB3 to LB0) to be
programmed and erased.
