Description
External Voltage Reference Input.
Port 0.0. See
Port 0.1. See
Power Supply Voltage.
Crystal Input. This pin is the external oscillator circuit return for a
crystal or ceramic resonator. See
Port 0.2. See
Crystal Input/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 network configurations. See
11.2.
Port 0.3. See
Port 0.4. See
Port 0.5. See
Clock signal for the C2 Development Interface.
Device Reset. Open-drain output of internal POR or VDD moni-
tor. An external source can initiate a system reset by driving this
pin low for at least 10 µs.
Port 0.6. See
ADC External Convert Start Input Strobe.
