Read Check Data

This command reads the check data that confirms that the write data, which was sent with the page

program command, was successfully received.

(1) Transfer the "FD16" command code with the 1st byte.

(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. After that, when the read

check command is executed again, the check data for all of the read data that was sent with the page

program command during this time is read. The check data is the result of CRC operation of write

data.
