PORTA is an 8-bit wide, bidirectional port. The corre-
sponding Data Direction and Output Latch registers are
TRISA and LATA.
RA4/T0CKI is a Schmitt Trigger input. All other PORTA
pins have TTL input levels and full CMOS output
drivers.
The RA4 pin is multiplexed with the Timer0 clock input
and one of the LCD segment drives. RA5 and RA<3:0>
are multiplexed with analog inputs for the A/D
Converter. RA1 is multiplexed with analog as well as
the LCD segment drive.
The operation of the analog inputs as A/D Converter
inputs is selected by clearing or setting the
ANSEL<3:0> control bits in the ANCON1 register. The
corresponding TRISA bits control the direction of these
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.

Note:
PORTA, TRISA and
LATA Registers
RA5 and RA<3:0> are configured as
analog inputs on any Reset and are read
as ‘0’. RA4 is configured as a digital input.

PIC18F87K90 FAMILY
OSC2/CLKO/RA6
serve as the external circuit connections for the exter-
nal (primary) oscillator circuit (HS Oscillator modes) or
the external clock input and output (EC Oscillator
modes). In these cases, RA6 and RA7 are not available
as digital I/O and their corresponding TRIS and LAT
bits are read as ‘0’. When the device is configured to
use HF-INTOSC, MF-INTOSC or LF-INTOSC as the
default oscillator mode, RA6 and RA7 are automatically
configured as digital I/O; the oscillator and clock
in/clock out functions are disabled.
RA1, RA4 and RA5 are multiplexed with LCD segment
drives that are controlled by bits in the LCDSE1 and
LCDSE2 registers. I/O port functionality is only
available when the LCD segments are disabled.
RA5 has additional functionality for Timer1 and Timer3.
It can be configured as the Timer1 clock input or the
Timer3 external clock gate input.
