CPU Mode bit 0. Input must be set to logic 0
(grounded); other encodings reserved.
CPU Mode bit 1. Input must be set to logic 0
(grounded); other encodings reserved.
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.
