Description
Port 0.3. See Port I/O Section for a complete description.
External Clock Output. For an external crystal or resonator, this pin
is the excitation driver. This pin is the external clock input for
CMOS, capacitor, or RC oscillator configurations. See Section
“14. Oscillators” on page 134.
Port 0.2. See Port I/O Section for a complete description.
External Clock Input. This pin is the external oscillator return for a
crystal or resonator. Section “14. Oscillators” on page 134.
Port 0.1. See Port I/O Section for a complete description.
