47
PF0
I/O
TTL
GPIO port F bit 0.
PhB0
I
TTL
QEI module 0 phase B.
48
OSC0
I
Analog Main oscillator crystal input or an external clock reference input.
49
OSC1
O
Analog Main oscillator crystal output. Leave unconnected when using a
single-ended clock source.
50
WAKE
I
TTL
An external input that brings the processor out of Hibernate mode
when asserted.
51
HIB
O
OD
An open-drain output with internal pull-up that indicates the
processor is in Hibernate mode.
52
XOSC0
I
Analog Hibernation module oscillator crystal input or an external clock
reference input. Note that this is either a 4.194304-MHz crystal or
a 32.768-kHz oscillator for the Hibernation module RTC. See the
CLKSEL bit in the HIBCTL register.
