Unimplemented. Reads as‘0’.
B3
RA3/AN3
GPIO or analog input. Returns value on pin RA3/AN3 when used as a digital
input. When congured as an analog input, reads as ‘0’.
B2
RA2/AN2
GPIO or analog input. Returns value on pin RA2/AN2 when used as a digital
input. When congured as an analog input, reads as ‘0’.
B1
RA1/AN1
GPIO or analog input. Returns value on RA1/AN1 when used as a digital input.
This pin can connect to a level shift network. If enabled, a +0.5V offset is added
to the input voltage. When congured as an analog input, reads as ‘0’.
B0
RA0/AN0
GPIO or analog input. Returns value on pin RA0/AN0 when used as a digital
input. When congured as an analog input, reads as ‘0’.

PORTC and TRISC
PORTC is a 8-bit wide bidirectional port, with Schmitt
Trigger inputs, that serves the following functions
depending on programming:
Direct LED drive (PORTC<7:0>).
I2C communication lines (PORTC<7:6>), refer to
Section 7.0 I2C Serial Port.
Interrupt on change function (PORTC<7:4>),
discussed below and in Section 10.3 Interrupts.
Programmable reference and comparator
outputs.
Timer0 clock source on RC3
The PORTC data register is located at location 07h and
its data direction register (TRISC) is at 87h.
PORTC<5:0> have weak internal pull-ups (~100 uA
typical). A single control bit can turn on all the pull-ups.
This is done by clearing bit RCPU (OPTION<7>). The
weak pull-up is automatically turned off when the port
pin is congured as an output. The pull-ups are
disabled on power-on reset and in hibernate mode.
When
using
PORTC<0>
as
an
analog
output
(CMCON<1> bit is set), the TRISC<0> bit should be
cleared to disable the weak pull-up on this pin. Refer to
Table 5-1.
Four of the PORTC pins, RC<7:4> have an interrupt on
change feature. Only pins congured as inputs can
cause this interrupt to occur. In other words, any pin
RC<7:4> congured as an output is excluded from the
interrupt on change comparison. The input pins of
RC<7:4> are compared with the old value latched on
the last read of PORTC. The “mismatch” outputs of
RC<7:4> are OR’ed together to assert the RCIF ag
(PIR1 register<2>) and cause a CPU interrupt, if
enabled.
Note:
If
the
I2C
function
is
enabled,
(I2CCON<5>, address 14h), RC<7:6> are
automatically
excluded
from
the
interrupt-on-change comparison.
