Procedure to Receive the MCU Information
Procedure to send inquiry commands, and receive the information necessary to send setting commands, program/erase
commands, and read-check commands is as follows.
(1) Send a support device inquiry command (20h) to check what type of endianness the MCU supports. The MCU
returns all device codes and series names that it supports.
(2) Send a user area information inquiry command (25h) to check the start and end addresses of the user area. The
MCU returns the start and end addresses of the user area.
(3) Send a block information inquiry command (26h) to check the block configuration. The MCU returns the start
address, the size of one block, and the number of blocks for the user area and data area.
(4) Send a data area information inquiry command (2Bh) to check the start and end addresses of the data area. The
MCU returns the start and end addresses of the data area.
