15.3.3 RE3 WEAK PULL-UP
The port RE3 pin has an individually controlled weak
internal pull-up. When set, the WPUE3 bit enables the
RE3 pin pull-up. When the RE3 port pin is configured
as MCLR, (CONFIG2L, MCLRE = 1 and CONFIG4H,
LVP = 0), or configured for Low-Voltage Programming,
(MCLRE = x and LVP = 1), the pull-up is always
enabled and the WPUE3 bit has no effect.
15.3.4 INTERRUPT-ON-CHANGE
The interrupt-on-change feature is available only on the
RE3 pin for all devices. For further details refer to
Section 14.11 “Interrupt-on-Change”.
