Read Lock Bit Status Command
This command reads the lock bit status of the specified block. Execute the read lock bit status com-
mand as explained here following.
(1) Send the “71
16
” command code in the 1st byte of the transmission.
(2) Send addresses A
8
to A
15
and A
16
to A
23
in the 2nd and 3rd bytes of the transmission respec-
tively.
(3) The lock bit data of the specified block is output in the 4th byte of the transmission. Write the
highest address of the specified block for addresses A
8
to A
23
.
The M30201 (flash memory version) does not have the lock bit, so the read value is always “1”
(block unlock).

Erase All Unlocked Blocks Command
This command erases the content of all blocks. Execute the erase all unlocked blocks command as
explained here following.
(1) Send the “A7
16
” command code in the 1st byte of the transmission.
(2) Send the verify command code “D0
16
” in the 2nd byte of the transmission. With the verify com-
mand code, the erase operation will start and continue for all blocks in the flash memory.
When block erasing ends, the
P5
3
(BUSY) signal changes from the “H” to the “L” level. The result of the
erase operation can be known by reading the status register.
