Program Acceleration via ACC Pin

The program acceleration function requires applying VHH to the ACC input, and then waiting a period of tWC.

Minimum tVHH (rise & fall times) is required for ACC to change to VHH from VIL or VIH. Removing VHH from the ACC

pin returns the device to normal operation after a period of tWC.

Only Read Status Register and Page Program operation are allowed when ACC is at (VHH).

The start address must be entered by the multiples of 4‐byte (for example xxxxx0, xxxxx4, xxxxx8, xxxxxC). Also the data

must be entered with a minimum of 4‐byte and multiples of 4‐byte unit when Program Acceleration via ACC Pin.
