functions may exist on one port pin. When multiplexing occurs, the peripheral module’s functional
requirements may force an override of the data direction (TRIS bit) of the port pin (such as in the
A/D and LCD modules).

LCD Voltage Generation
LCD Voltage Generation
Capture1 input/Compare1 output/PWM1 output
Capture2 input/Compare2 output/PWM2 output.
A/D ramp current source output. Normally connected to external
capacitor to generate a linear voltage ramp.
USART Synchronous Clock, always associated with TX pin function
(See related TX, RX, DT)
External clock source input. Always associated with pin function
OSC1. (See related OSC1/CLKIN, OSC2/CLKOUT pins)
Oscillator crystal output. Connects to crystal or resonator in crystal
oscillator mode. In RC mode, OSC2 pin outputs CLKOUT which has
1/4 the frequency of OSC1, and denotes the instruction cycle rate.
Always associated with OSC2 pin function. (See related OSC2,
