Description
2.7–3.6 V Core Supply Voltage Input.
3.3 V Voltage Regulator Output. See Section 5.
V I/O Supply Voltage Input. The voltage at this pin must be
less than or equal to the Core Supply Voltage (V
'F326. On the 'F327, this pin is internally connected to V
Ground.
Device Reset. Open-drain output of internal POR or VDD
monitor. An external source can initiate a system reset by
driving this pin low for at least 15 µs. See Section 7.
Clock signal for the C2 Debug Interface.
Port 3.0. See Section 11 for a complete description.
Bi-directional data signal for the C2 Debug Interface.
5 V Regulator Input. This pin is the input to the on-chip volt-
age regulator.
VBUS Sense Input. This pin should be connected to the
VBUS signal of a USB network. A 5 V signal on this pin indi-
cates a USB network connection.
