10. Lock Bit Disable Command
This command disables the lock bit for all blocks. Figure 1.170 shows the lock bit disable command timing. The
command code "75
function; it does not set the lock bit itself. However, if an erase command is executed after executing the lock bit disable
command, all "0" (locked) lock bit data is set to "1" (unlocked) after the erase operation ends. After reset the lock bit is
always enabled.
11. ID Check Command
This command checks the ID code. Figure 1.171 shows the ID check command timing. To execute the boot ID check
command:
(1) Transfer the "F5
(2) Transfer addresses A
respectively.
(3) Transfer the number of data sets of the ID code with the 5th byte.
(4) The ID code is sent with the 6th byte on, starting with the 1st byte of the code.
See the ID code section for more information.
