4.2
Every PORTA pin on the PIC16F610/616/16HV610/
616 has an interrupt-on-change option and a weak pull-
up option. The next three sections describe these
functions.
4.2.1
The ANSEL register is used to configure the Input
mode of an I/O pin to analog. Setting the appropriate
ANSEL bit high will cause all digital reads on the pin to
be read as ‘0’ and allow analog functions on the pin to
operate correctly.
The state of the ANSEL bits has no affect on digital
output functions. A pin with TRIS clear and ANSEL set
will still operate as a digital output, but the Input mode
will be analog. This can cause unexpected behavior
when executing read-modify-write instructions on the
affected port.
4.2.2
Each of the PORTA pins, except RA3, has an
individually configurable internal weak pull-up. Control
bits WPUAx enable or disable each pull-up. Refer to
Register 4-4. Each weak pull-up is automatically turned
off when the port pin is configured as an output. The
pull-ups are disabled on a Power-on Reset by the
RAPU bit of the OPTION register). A weak pull-up is
automatically enabled for RA3 when configured as
MCLR and disabled when RA3 is an I/O. There is no
software control of the MCLR pull-up.

Additional Pin Functions
Setting a pin to an analog input automatically disables the digital input circuitry, weak pull-ups, and
interrupt-on-change if available. The corresponding TRIS bit must be set to Input mode in order to allow
external control of the voltage on the pin.

4.2.3
Each PORTA pin is individually configurable as an
interrupt-on-change pin. Control bits IOCAx enable or
disable the interrupt function for each pin. Refer to
Register 4-5. The interrupt-on-change is disabled on a
Power-on Reset.
For enabled interrupt-on-change pins, the values are
compared with the old value latched on the last read of
PORTA. The ‘mismatch’ outputs of the last read are
OR’d together to set the PORTA Change Interrupt Flag
bit (RAIF) in the INTCON register (Register 2-3).
This interrupt can wake the device from Sleep. The
user, in the Interrupt Service Routine, clears the
interrupt by:
a)
b)
A mismatch condition will continue to set flag bit RAIF.
Reading PORTA will end the mismatch condition and
allow flag bit RAIF to be cleared. The latch holding the
last read value is not affected by a MCLR nor BOR
Reset. After these resets, the RAIF flag will continue to
be set if a mismatch is present.

Note:
.
Any read or write of PORTA. This will end the
mismatch condition, then,
Clear the flag bit RAIF.
INTERRUPT-ON-CHANGE
If a change on the I/O pin should occur
when any PORTA operation is being
executed, then the RAIF interrupt flag may
not get set.
