Description
Digital Supply Voltage. Must be tied to +2.7 V to +3.6 V
power.
Analog Supply Voltage. Must be tied to +2.7 V to +3.6 V
power.
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 15 µs. A 1kΩ pull-up to V
recommended. See Reset Sources Section.
Clock signal for the C2 Debug Interface.
Port 2.0. See Port I/O Section for a complete description.
