Description
Power Supply Voltage.
Ground.
Device Reset. Open-drain output of internal POR. An
external source can initiate a system reset by driving
this pin low for at least 10 µs.
Clock signal for the C2 Debug Interface.
Port 3.0. See
Bi-directional data signal for the C2 Debug Interface.
Port 0.0. See
External VREF input. (‘F310/1/2/3 only)
Port 0.1. See
Port 0.2. See
External Clock Input. This pin is the external oscillator
return for a crystal or resonator.
Port 0.3. See
External Clock Output. For an external crystal or reso-
nator, this pin is the excitation driver. This pin is the
external clock input for CMOS, capacitor, or RC oscil-
lator configurations.
