while output data is shifted out on the falling edge of the clock input.
SI Serial Data Input To transfer commands, addresses, or data serially into the device.
Inputs are latched on the rising edge of the serial clock.
SO Serial Data Output To transfer data serially out of the device.
Data is shifted out on the falling edge of the serial clock.
Outputs Flash busy status during AAI Programming when reconfigured as RY/BY# pin.
See “Hardware End-of-Write Detection” on page 12 for details.
