17.28.4 Auto-Program Mode
(1) In auto-program mode, programming is in 128-byte units. That is, 128 bytes of data are
(2) Even in the programming of less than 128 bytes, 128 bytes of data must be transferred. H'FF

(4) The memory address is transferred in the 2nd cycle. Do not transfer addresses in the 3rd or

Timing in PROM Mode.
17.28.5 Auto-Erase Mode
(1) Auto-erase mode only supports erasing of the entire memory.
(2) Do not perform command writing during auto erasing is in progress.
(3) To confirm the end of automatic erasing, check the signal on the I/O
