15. Read Check Data
This command reads the check data, that confirms that the write data, sent with the page program command, was
successfully received. Figure 1.194 shows the read check data timing. To execute the read check data:
(1) Transfer the "FD
(2) The check data (low) is received with the 2nd byte and the check data (high) with the 3rd.
To use this read check data command, first execute the command and then initialize the check data. Next, execute the
page program command the required number of times. Afterwards, when the read check command is executed again,
the check data (for all of the read data sent with the page program command during this time) is read. The check data
is the result of a CRC operation of write data.
16. Baud Rate 9600
This command changes the baud rate to 9,600 bps. Figure 1.195 shows the baud rate 9600 command timing. To
execute the baud rate 9600 bps command:
(1) Transfer the "B0
(2) After the "B0
17. Baud Rate 19200
This command changes the baud rate to 19,200 bps. Figure 1.196 shows the baud rate 19200 command timing. To
execute the baud rate 19200 bps command:
(1) Transfer the "B1
(2) After the "B1
