14. Boot ROM Area Output Command
This command outputs the control program stored in the boot ROM area in one page blocks (256 bytes). Figure 1.174
shows the boot ROM area output timing. To execute the boot ROM area output command:
(1) Transfer the "FC
(2) Transfer addresses A
(3) Starting with the 4th byte, data (D0-D7) for the page (256 bytes) specified by addresses A
sequentially from the smallest address first, in sync with the falling edge of the transfer clock.
15. Read Check Data command
This command reads the check data that confirms that the write data, sent with the page program command, has been
successfully received. Figure 1.175 shows the read check data timing. To execute the read check data command:
(1) Transfer the "FD
(2) The check data (low) is received with the 2nd byte and the check data (high) with the 3rd byte.
To use this read check data command, first execute the command and then initialize the check data. Then 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 that was sent with the page program command during this time) is read. The
check data is the result of a CRC operation of write data.
