REGISTER 10-4:
10.2
PORTA is a 7-bit wide, bidirectional port. It may
function as a 5-bit port, depending on the oscillator
mode selected. 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 (LATA) register is also memory mapped.
Read-modify-write operations on the LATA register read
and write the latched output value for PORTA.
The other PORTA pins are multiplexed with analog
inputs, the analog V
parator voltage reference output. The operation of pins,
RA<3:0> and RA5, as A/D Converter inputs is selected
by clearing or setting the control bits in the ADCON0
register (A/D Port Configuration Register 0).
Pins, RA0, RA2, and RA3, may also be used as com-
parator inputs and by setting the appropriate bits in the
CMCON register. To use RA<3:0> as digital inputs, it is
also necessary to turn off the comparators.

PORTA, TRISA and LATA Registers
To enable the actual RTCC output, the RTCOE (RTCCFG<2>) bit needs to be set.
On a Power-on Reset (POR), RA5 and
RA<3:0> are configured as analog inputs
and read as ‘0’.
Unimplemented: Read as ‘0’

PIC18F47J53 FAMILY
All PORTA pins have TTL input levels and full CMOS
output drivers.
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.
