and
The DATA output signal transfers data serially out of the serial
configuration device to the FPGA during read/configuration operation.
During read/configuration operations, the serial configuration device
is enabled by pulling nCS low. The DATA signal transitions on the
falling edge of DCLK.
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 on the rising edge
of DCLK.
