Digital and power supply ground
Pacer Clock Output. This pin pulses once for
each pacer clock when turned on. If A/D conver-
sion is in the pacer trigger mode, this signal can
be used as a synchronous signal for other appli-
cations. A low - to- high edge triggers A/D con-
version to start.
Counter 0 Gate
A/D External Tirgger. This pin is external trigger
signal input for the A/D conversion. A low-to-
high edge triggers A/D conversion to get one
sample.
