19.22.5 Auto-Program Mode
In auto-program mode, 128 bytes are programmed simultaneously. For this purpose, 128 consecutive byte data
transfers should be performed.
A 128-byte data transfer must be performed even if writing fewer than 128 bytes; in this case, H'FF data must be
written to the extra addresses.
The lower 7 bits of the transfer address must be held low. If an invalid address is input, memory programming will be
started but a programming error will occur.
Memory address transfer is executed in the second cycle (figure 19-59). Do not perform transfer later than the second
cycle.
Do not perform a command write during a programming operation.
Perform one auto-programming operation for a 128-byte block for each address. One or more additional programming
operations cannot be carried out on address blocks that have already been programmed.
Confirm normal end of auto-programming by checking I/O
