I/O PORT
As with any other register, the I/O register(s) can be
written and read under program control. However, read
instructions (e.g., MOVF GPIO, W) always read the I/O
pins independent of the pin’s Input/Output modes. On
Reset, all I/O ports are defined as input (inputs are at
high-impedance) since the I/O control registers are all
set.
5.1
GPIO
GPIO is an 8-bit I/O register. Only the low-order 4 bits
are used (GP<3:0>). Bits 7 through 4 are unimple-
mented and read as ‘0’s. Please note that GP3 is an
input only pin. Pins GP0, GP1 and GP3 can be config-
ured with weak pull-ups and also for wake-up on
change. The wake-up on change and weak pull-up
functions are not individually pin selectable. If GP3/
MCLR is configured as MCLR, a weak pull-up can be
enabled via the Configuration Word. Configuring GP3
as MCLR disables the wake-up on change function for
this pin.
5.2
TRIS Registers
The Output Driver Control register is loaded with the
contents of the W register by executing the TRIS f
instruction. A ‘1’ from a TRIS register bit puts the corre-
sponding output driver in a High-Impedance mode. A
‘0’ puts the contents of the output data latch on the
selected pins, enabling the output buffer. The excep-
tions are GP3, which is input only, and the GP2/T0CKI/
FOSC4 pin, which may be controlled by various
registers. See Table 5-1.
The TRIS registers are “write-only” and are set (output
drivers disabled) upon Reset.
5.3
I/O Interfacing
The equivalent circuit for an I/O port pin is shown in
Figure 5-1. All port pins, except GP3, which is input
only, may be used for both input and output operations.
For input operations, these ports are non-latching. Any
input must be present until read by an input instruction
(e.g., MOVF GPIO, W). The outputs are latched and
remain unchanged until the output latch is rewritten. To
use a port pin as output, the corresponding direction
control bit in TRIS must be cleared (= 0). For use as an
input, the corresponding TRIS bit must be set. Any I/O
pin (except GP3) can be programmed individually as
input or output.

FOR A SINGLE I/O PIN

ORDER OF PRECEDENCE FOR PIN FUNCTIONS
TABLE 5-2:
REQUIREMENTS TO MAKE PINS AVAILABLE IN DIGITAL MODE
Note:
A read of the ports reads the pins, not the
output data latches. That is, if an output
driver on a pin is enabled and driven high,
but the external system is holding it low, a
read of the port will indicate that the pin is
low.
