Block Erase Command
Erase All Code Blocks Command
(M16C reception data)
(M16C transmit data)
This command erases the data in the specified block. Execute the block erase command as explained
here following.
When block erasing ends, the RTS
erase ends, the result of the block erase operation can be known by reading the status register. For
more information, see the section on the status register.
Each block can be erase-protected with the lock bit. For more information, see the section on the data
protection function.
This command erases the content of all code blocks. Execute the erase all code blocks command as
explained here following.
When block erasing ends, the RTS1 (BUSY) signal changes from the “H” to the “L” level. The result of
the erase operation can be known by reading the status register.
(1) Transfer the “20
(2) Transfer addresses A
(3) Transfer the verifycommand code “D0
(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 for the specified block in the flash memory. Write the highest address of
the specified block for addresses A
erase operation will start and continue for all code blocks in the flash memory.
