9.0
Depending on the device selected, there are up to 9
ports available. Some pins of the I/O ports are multi-
plexed with an alternate function from the peripheral
features 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
• 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.
9.1
PORTA is a 6-bit wide, bi-directional 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
Hi-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).
On a Power-on Reset, these pins are configured as
analog inputs and read as '0'.
Reading the PORTA register reads the status of the
pins, whereas writing to it will write to the port latch.
Read-modify-write operations on the LATA register,
reads and writes 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 other PORTA pins are multiplexed with analog
inputs and the analog V
operation of each pin is selected by clearing/setting the
control bits in the ADCON1 register (A/D Control
Register1). On a Power-on Reset, these pins are con-
figured as analog inputs and read as '0'.
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.
