Description
Positive supply for most of the logic function,
including the processor core and most peripherals.
The positive supply (3.3 V) for the analog circuits
(ADC, Analog Comparators, etc.). These are
separated from VDD to minimize the electrical noise
contained on VDD from affecting the analog
functions.

An external input that brings the processor out of
hibernate mode when asserted.

Main oscillator crystal input or an external clock
reference input.
Main oscillator crystal output.
System reset input.
JTAG TRSTn
Hibernation Module oscillator crystal input or an
external clock reference input. Note that this is
either a 4.19-MHz crystal or a 32.768-kHz oscillator
for the Hibernation Module RTC. See the CLKSEL
bit in the HIBCTL register.
Hibernation Module oscillator crystal output.
UART module 0 receive. When in IrDA mode, this
signal has IrDA modulation.
UART module 0 transmit. When in IrDA mode, this
signal has IrDA modulation.
UART module 1 receive. When in IrDA mode, this
signal has IrDA modulation.
