2.7 Suspends Serial Input (HOLD)

The HOLD pin is used in conjunction with the CS pin to pause the AT25320B/AT25640B. When the device is selected and a serial sequence is underway, HOLD can be used to pause the serial communication with the host device without resetting the serial sequence. To pause, the HOLD pin must be brought low while the SCK pin is low. To resume serial communication, the HOLD pin is brought high while the SCK pin is low (SCK may still toggle during HOLD). Inputs to the SI pin will be ignored while the SO pin is in the high-impedance state.
