Function
Analog Signal Input
Start Convert. A high-to-low transition on
this input begins the conversion cycle and
enables serial data output.
Clock that drives A/D conversion cycle and
the synchronous serial data output
Serial Data. Tri-state serial data output for
the A/D result driven by the CLOCK input
