qBlock Erase Command
This command erases the contents of the specifided block. Ex-
ecute the block erase command as explained here following.
(1) Transfer the “2016” command code with the 1st byte.
(2) Transfer addresses AB8 to AB15 and AB16 to AB23 with the 2nd
and 3rd bytes respectively.
(3) Transfer the verify command code “D016” with the 4th byte.
With the verify command code, the erase operation will start
for the specifided block in the flash memory. Set the addresses
AB8 to AB23 to the maximum address of the specified block.

When block erasing ends, the SRDY (BUSY) signal changes from
“H” to “L” level. The result of the erase operation can be known by
reading the status register.
For more information, see the section on the status register.

qErase All Blocks Command
This command erases the contents of all blocks. Execute the
erase all blocks command as explained here following.
(1) Transfer the “A716” command code with the 1st byte.
(2) Transfer the verify command code “D016” with the 2nd byte.
With the verify command code, the erase operation will start
and continue for all blocks in the flash memory.
When erase all blocks end, the SRDY (BUSY) signal changes
from “H” to “L” level. The result of the erase operation can be
known by reading the status register.
