Analog Output Ground—The AO
—
voltages and the external reference voltage
are referenced to these pins.
Analog Output channels 0 through
31—These pins supply the voltage outputs
of their respective channels.
Digital Ground—These pins supply the
—
reference for the digital signals at the I/O
connector as well as the +5 VDC supply.
Digital I/O signals—These pins drive and
receive digital signals. P0.6 and P0.7 can
control the up/down signal of Counters 0
and 1, respectively.
