PORT B ANALOG
The eight port A pins can be used as analog inputs, or as a bi-directional 8-bit digital
input/output port.
When used as analog inputs, the eight port A pins are referred to as AN[59:52]. Due
to the digital output drivers associated with port A, the analog characteristics of port A
are different from those of port B. All of the analog signal input pins may be used for
at least one other purpose.
Port A pins are referred to as PQA when used as a bidirectional 8-bit digital input/out-
put port. These eight pins may be used for general-purpose digital input signals or dig-
ital output signals.
