periods, this pin is used as the conversion status output.
The conversion status can be observed by pulling CS LOW.
SCK (Pin 13): Bidirectional Digital Clock Pin. In Internal
Serial Clock Operation mode, SCK is used as digital output
for the internal serial interface clock during the Data
Output period. In External Serial Clock Operation mode,
SCK is used as digital input for the external serial interface
clock during the Data Output period. A weak internal pull-
up is automatically activated in Internal Serial Clock Op-
eration mode. The Serial Clock Operation mode is deter-
mined by the logic level applied to the SCK pin at power up
or during the most recent falling edge of CS.
