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
Used in Host mode to control an external power
source to supply power to the USB bus.
Used in Host mode by an external power source
to indicate an error state by that power source.
