Non maskable interrupt
Main oscillator crystal input or an external clock
reference input.
Main oscillator crystal output.
System reset input.
Bidirectional differential data pin (D- per USB
specification).
Bidirectional differential data pin (D+ per USB
specification).
9.1 KOhm resistor (1% precision) used internally
for USB analog circuitry.
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 1 receive
UART 1 transmit
