Continuous Read Mode Reset (CRMR) (FFH)

The Dual/Quad I/O Fast Read

operations, “Continuous Read Mode” bits (M7-0) are implemented to further reduce

command overhead. By setting the (M7-0) to AXH, the next Dual/Quad I/O Fast Read operations do not require the

BBH/EBH/E7H command code.

Because the GD25B16C has no hard

ware reset pin, so if Continuous Read Mode bits are set to “AXH”, the GD25B16C

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

Figure28.
