Description
Power Supply Voltage.
Ground.
This ground connection is required. The center pad may
optionally be connected to ground also.
Device Reset. Open-drain output of internal POR or V
monitor. 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.
Bi-directional data signal for the C2 Debug Interface.
Shared with P2.0 on 20-pin packaging and P2.4 on 24-pin
packaging.
Port 0.0.
External VREF input.
Port 0.1.
IDA0 Output.
Port 0.2.
External Clock Input. This pin is the external oscillator
return for a crystal or resonator.
Port 0.3.
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.
