Description
UART module 1 receive. When in IrDA mode,
this signal has IrDA modulation.
UART module 1 transmit. When in IrDA mode,
this signal has IrDA modulation.
UART 2 Receive. When in IrDA mode, this
signal has IrDA modulation.
UART 2 Transmit. When in IrDA mode, this
signal has IrDA modulation.
Power source for the Hibernation Module. It
is normally connected to the positive terminal
of a battery and serves as the battery
backup/Hibernation Module power-source
supply.

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.
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.
