17.11.5 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 17.26). Do not perform
• Do not perform a command write during a programming operation.
