Port A is an 8-bit I/O port. All A pins have Schmitt triggers on the inputs. The 44-pin package does not
have a full 8-bit port and contains some unbonded, floating pads internally on the chip. The binary value
read from these bits is undetermined. The application software should mask out these unknown bits when
reading the Port A register, or use only bit-access program instructions when accessing Port A. These
unconnected bits draw power only when they are addressed (i.e., in brief spikes). Additionally, if Port A is
being used with some combination of digital inputs and analog inputs, the analog inputs will read as
undetermined values and should be masked out by software.
Port A supports the analog inputs for the A/D converter. Port A has the following alternate pin functions:
A7
Analog Channel 7
A6
Analog Channel 6
A5
Analog Channel 5
A4
Analog Channel 4
A3
Analog Channel 3
A2
Analog Channel 2
A1
Analog Channel 1
A0
Analog Channel 0
Port B is an 8-bit I/O port. All B pins have Schmitt triggers on the inputs. If Port B is being used with some
combination of digital inputs and analog inputs, the analog inputs will read as undetermined values. The
application software should mask out these unknown bits when reading the Port B register, or use only bit-
access program instructions when accessing Port B.
Port B supports the analog inputs for the A/D converter. Port B has the following alternate pin functions:
B7
Analog Channel 15 or A/D Input
B6
Analog Channel 14 or Analog Multiplexor Output
B5
Analog Channel 13 or Analog Multiplexor Output
B4
Analog Channel 12
B3
Analog Channel 11
B2

B0
Analog Channel 8
Port C is an 8-bit I/O port. The 44-pin device does not offer Port C. The unavailable pins are not
terminated. A read operation on these unterminated pins will return unpredictable values. On this device,
the associated Port C Data and Configuration registers should not be used. All C pins have Schmitt
triggers on the inputs. Port C draws no power when unbonded.
