The AS data input signal is used to transfer data serially into the
serial configuration device. It receives the data that should be
programmed into the serial configuration device. Data is latched

The active low chip select input signal toggles at the beginning
and end of a valid instruction. When this signal is high, the
device is deselected and the
signal is low, it enables the device and puts the device in an
active mode. After power up, the serial configuration device
requires a falling edge on the
