I/O PORTS
Depending on the device selected, there are either
seven or nine I/O ports available on PIC18FXX20
devices. Some of their pins are multiplexed with one or
more alternate functions from the other peripheral fea-
tures on the device. In general, when a peripheral is
enabled, that pin may not be used as a general
purpose I/O pin.
Each port has three registers for its operation. These
registers are:
TRIS register (data direction register)
PORT register (reads the levels on the pins of the
device)
LAT register (output latch)
The Data Latch (LAT register) is useful for read-modify-
write operations on the value that the I/O pins are
driving.
A simplified version of a generic I/O port and its
operation is shown in Figure 10-1.

PORTA, TRISA and LATA
Registers
PORTA is a 7-bit wide, bidirectional port. The corre-
sponding data direction register is TRISA. Setting a
TRISA bit (= 1) will make the corresponding PORTA pin
an input (i.e., put the corresponding output driver in a
high-impedance mode). Clearing a TRISA bit (= 0) will
make the corresponding PORTA pin an output (i.e., put
the contents of the output latch on the selected pin).
Reading the PORTA register reads the status of the
pins, whereas writing to it will write to the port latch.
The Data Latch register (LATA) is also memory
mapped. Read-modify-write operations on the LATA
register, read and write the latched output value for
PORTA.
The RA4 pin is multiplexed with the Timer0 module
clock input to become the RA4/T0CKI pin. The RA4/
T0CKI pin is a Schmitt Trigger input and an open-drain
output. All other RA port pins have TTL input levels and
full CMOS output drivers.
The RA6 pin is only enabled as a general I/O pin in
ECIO and RCIO Oscillator modes.
The other PORTA pins are multiplexed with analog
inputs and the analog VREF+ and VREF- inputs. The
operation of each pin is selected by clearing/setting the
control bits in the ADCON1 register (A/D Control
Register 1).
The TRISA register controls the direction of the RA
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.
