3. Block Erase Command
This command erases all the data in the specified block. Figure 1.182 shows the block erase timing. To execute the
block erase command:
(1) Transfer the "20
(2) Transfer addresses A
(3) Transfer the verify command code "D0
start for the specified block in the flash memory. Write the highest address of the specified block for addresses A
After block erase ends, the results of the block erase operation can be reviewed in the status register. Refer to the status
register section for more details. Each block can be erase-protected with the lock bit. Refer to the data protection
function section for more details.
4. Erase All Unlocked Blocks Command
This command erases the content of all blocks. Figure 1.183 shows the erase all unlocked blocks timing. To
execute the erase all unlocked blocks command:
(1) Transfer the "A7
(2) Transfer the verify command code "D0
will start and continue for all blocks in the flash memory.
The results of the erase operation can be reviewed in the status register. Each block can be erase-protected with the
lock bit. Refer to the data protection function and status register sections for more details.
