Section 18 Flash Memory [H8/3024F-ZTAT Version]
18.3.3
EBR is an 8-bit register that designates the flash memory block for erasure. EBR is initialized to
H'00 by a reset, in hardware standby mode or software standby mode, when a high level is not
input to the FWE pin, or when the SWE bit in FLMCR1 is 0 when a high level is applied to the
FWE pin. When a bit is set in EBR, the corresponding block can be erased. Other blocks are erase-
protected. The blocks are erased block by block. Therefore, set only one bit in EBR; do not set bits
in EBR to erase two or more blocks at the same time.
Each bit in EBR cannot be set until the SWE bit in FLMCR1 is set. The flash memory block
configuration is shown in table 18.4. To erase all the blocks, erase each block sequentially.
The H8/3024F-ZTAT version does not support the on-board programming mode in mode 6, so
bits in this register cannot be set to 1 in mode 6.
Bits 7 to 0—Block 7 to Block 0 (EB7 to EB0): Setting one of these bits specifies the
corresponding block (EB7 to EB0) for erasure.

Note: When not performing an erase, clear all EBR bits to 0.
