Introduction
General purpose I/O pins can be considered the simplest of peripherals. They allow the
PICmicro™ to monitor and control other devices. To add flexibility and functionality to a device,
some pins are multiplexed with an alternate function(s). These functions depend on which
peripheral features are on the device. In general, when a peripheral is functioning, that pin may
not be used as a general purpose I/O pin.
For most ports, the I/O pin’s direction (input or output) is controlled by the data direction register,
called the TRIS register. TRIS<x> controls the direction of PORT<x>. A ‘1’ in the TRIS bit corre-
sponds to that pin being an input, while a ‘0’ corresponds to that pin being an output. An easy
way to remember is that a ‘1’ looks like an I (input) and a ‘0’ looks like an O (output).
The PORT register is the latch for the data to be output. When the PORT is read, the device reads
the levels present on the I/O pins (not the latch). This means that care should be taken with
read-modify-write commands on the ports and changing the direction of a pin from an input to an
output.

be multiplexed onto the I/O pin. Reading the PORT register reads the status of the pins whereas
writing to it will write to the port latch. All write operations (such as BSF and BCF instructions) 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.
