7.19 Enable/Disable SO to Output RY/BY# (ESRY/DSRY) (70H/80H)

Besides SO pin is used to output data, it also can be used as the status pin of ready/busy. The ESRY command is for

outputting the ready/busy status to SO. When the device is in the process of power on, enter or exit deep power down

mode and erase/program, its status is busy, and the SO output 0. When the device is in the standby mode, the status of

device is ready, then SO output 1. The DSRY command is for resetting ESRY. The ready/busy status will not output to SO

after DSRY issued.

The Enable/Disable SO to Output RY/BY# command sequence:

CS# goes low → sending ESRY command code → CS#

goes high. The command sequence is shown in Figure21. CS# must be driven high after the eighth bit of the command

code has been latched in; otherwise the Enable/Disable SO to Output RY/BY# command is not executed.
