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
