While PWRON_RESET_N is deasserted use Power On Reset column for the pin state.
After deassertion of PWRON_RESET_N, and deassertion of RESET_IN_N, and assertion of
PLL_LOCK, all signals reflect the value shown in the RESET column.

General purpose Input/Output pins. May be configured as an input
or an output. As an input, each signal may be configured a
processor interrupt. Default after reset is to be configured as inputs.
Should be pulled low using a 10-K: resistor when not being utilized
in the system.
33.33 MHz, sinusoidal crystal input signal. Can be driven by an
oscillator.
33.33 MHz, sinusoidal crystal output signal. Left disconnected
when being driven by an oscillator.
