Notes on Use of Auto-Program Mode
Rev.6.00 Oct.28.2004 page 610 of 1016
REJ09B0138-0600H
In auto-program mode, 128 bytes are programmed simultaneously. This should be carried out by executing 128
consecutive byte transfers.
A 128-byte data transfer is necessary even when programming fewer than 128 bytes. In this case, H'FF data must be
written to the extra addresses.
The lower 8 bits of the transfer address must be H'00 or H'80. If a value other than an effective address is input,
processing will switch to a memory write operation but a write error will be flagged.
Memory address transfer is performed in the second cycle (figure 19-29). Do not perform memory address transfer
after 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. Characteristics are not guaranteed for
two or more programming operations.
Confirm normal end of auto-programming by checking I/O
