Cautions on Use of Auto-Program Mode
Rev. 4.00 Jan 26, 2006 page 652 of 938
REJ09B0276-0400
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.
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 18.20). Do not perform
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 6. Alternatively, status read mode
can also be used for this purpose.
