4.0
There are as many as eleven general purpose I/O pins
and an input pin available. Depending on which
peripherals are enabled, some or all of the pins may not
be available as general purpose I/O. In general, when a
peripheral is enabled, the associated pin may not be
used as a general purpose I/O pin.
4.1
PORTA is a 6-bit wide, bidirectional port. The
corresponding
(Register 4-2). Setting a TRISA bit (= 1) will make the
corresponding PORTA pin an input (i.e., disable the
output driver). Clearing a TRISA bit (= 0) will make the
corresponding PORTA pin an output (i.e., enables output
driver and puts the contents of the output latch on the
selected pin). The exception is RA3, which is input only
and its TRIS bit will always read as ‘1’. Example 4-1
shows how to initialize PORTA.
Reading the PORTA register (Register 4-1) reads the
status of the pins, whereas writing to it will write to the
PORT latch. All write operations are read-modify-write
operations. Therefore, a write to a port implies that the

port pins are read, this value is modified and then
written to the PORT data latch. RA3 reads ‘0’ when
MCLRE = 1.
The TRISA register controls the direction of the
PORTA pins, even when they are being used as
analog inputs. The user must ensure the bits in the
TRISA register are maintained set when using them as
analog inputs. I/O pins configured as analog input
always read ‘0’.
