lim Boot Area Output Command

This command outputs the control program stored in the boot area in one page blocks (256 bytes).

Execute the boot area output command as explained here following.

(1) Send the “FC16” command code in the 1st byte of the transmission.

(2) Send addresses A8 to A15 and A16 to A23 in the 2nd and 3rd bytes of the transmission respec-

tively.

e (3) From the 4th byte onward, data (D0–D7) for the page (256 bytes) specified with addresses A8 to

PrA23 will be output sequentially from the smallest address first, in sync with the rise of the clock.
