3. Block Erase Command
This command erases the data in the specified block. Figure 1.163 shows the block erase timing.
To execute the block erase command:
(1) Transfer the "20
(2) Transfer addresses A
specified block for addresses A
(3) Transfer the verify command code "D0
start for the specified block in the flash memory.
When the block erase is finished, the RTS1 (BUSY) signal changes from the "H" to the "L" level. The status register
shows the results of the block erase command. Refer to the status register section for more details.
Each block is erase-protected with the lock bit. Refer to the data protection section for more details.
4. Erase All Unlocked Blocks Command
This command erases the contents of all blocks. Figure 1.164 shows the timing for erasing all unlocked blocks. To
execute the erase all unlocked blocks command:
(1) Transfer the "A7
(2) Transfer the verify command code "D0
continue for all of the flash memory.
When block erasing ends, the RTS1 (BUSY) signal changes from the "H" to the "L" level The status register shows the
results of the erase all unlocked blocks command. Refer to the status register section for more details.
Each block is erase-protected with the lock bit. Refer to the data protection section for more details.
