This command reads the check data that confirms that the write data, which was sent with the page
program command, was successfully received.
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.
