Note 1: For the WPUB register setting to take effect, the RBPU bit in the OPTION_REG
2: The weak pull-up device is automatically disabled if the pin is in Output mode
The interrupt enable bits GIE and RBIE in the INTCON Register must be set for indi-
vidual interrupts to be recognized.
register must be cleared.
