ACE25AA320G

Serial NOR Flash Memory

3.0V Multi I/O with 4KB, 32KB & 64KB Sector/Block Erase

VER 1.2

Because the ACE25AA320G has no hardware reset pin, so if Continuous Read Mode bits are set to

“AXH”, the ACE25AA320G will not recognize any standard SPI commands. So Continuous Read Mode

Reset command will release the Continuous Read Mode from the “AXH” state and allow standard SPI

command to be recognized. The command sequence is show in Figure32.

Disable QPI (FFH)

To exit the QPI mode and return to Standard/Dual/Quad SPI mode, the “Disable QPI (FFH)” command

must be issued. When the device is switched from QPI mode to SPI mode, the existing Write Enable

Latch and Program/Erase Suspend status, and the Wrap Length setting will remain unchanged. When the

device is in QPI mode, the first FFH command will exit continuous read mode and the second FFH

command will exit QPI mode.
