A/D ramp current source output. Normally connected to
external capacitor to generate a linear voltage ramp.
Analog input channel 0. This pin can also serve as a
general-purpose I/O.
Analog input channel 1. This pin can connect to a level
shift network. If enabled, a +0.5V offset is added to the
input voltage. This pin can also serve as a general-
purpose I/O.
Analog input channel 2. This pin can also serve as a
general purpose digital I/O.
Analog input channel 3. This pin can also serve as a gen-
eral purpose digital I/O.
AN1 summing junction output. This pin can be connected
to an external capacitor for averaging small duration
pulses.
LED direct-drive output or programmable reference A out-
put. This pin can also serve as a GPIO. If enabled, this
pin has a weak internal pull-up to V
