19.11.4 Auto-Program Mode
1. In auto-program mode, 128 bytes are programmed simultaneously. This should be carried out
2. A 128-byte data transfer is necessary even when programming fewer than 128 bytes. In this
3. The lower 7 bits of the transfer address must be low. If a value other than an effective address
4. Memory address transfer is performed in the second cycle (figure 19.22). Do not perform
5. Do not perform a command write during a programming operation.
6. Perform one auto-program operation for a 128-byte block for each address. Two or more
7. Confirm normal end of auto-programming by checking I/O6. Alternatively, status read mode
8. Status polling I/O6 and I/O7 pin information is retained until the next command write. As long
