19.20.5 Auto-Program Mode
• In auto-program mode, 128 bytes are programmed simultaneously. For this purpose, 128
• A 128-byte data transfer must be performed even if writing fewer than 128 bytes; in this case,
• The lower 7 bits of the transfer address must be held low. If an invalid address is input,
• Memory address transfer is executed in the second cycle (figure 19.52). Do not perform
• 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
• Confirm normal end of auto-programming by checking I/O
