The OPA module is enabled by setting the OPAON bit
(OPAxCON<7>). When enabled, OPAON forces the
output driver of RC3/AN7/C12IN3-/OP1 for OPA1, and
RC2/AN6/C12IN2-/OP2 for OPA2, into tri-state to pre-
vent contention between the driver and the OPA output.

When OPA1 or OPA2 is enabled, the
RC3/AN7/C12IN3-/OP1 pin, or
RC2/AN6/C12IN2-/OP2 pin respectively, is
driven by the op amp output, not by the
PORTC driver. Refer to the Electrical
specifications for the op amp output drive
capability.
