Software Defined Pin. The Software Defined Pins are reserved and programmable
with respect to input and output capability. These default to input signals upon power-
up but may be configured differently by the EEPROM. The upper four bits may be
mapped to the General Purpose Interrupt bits if they are configured as input signals.
Crystal One. The Crystal One pin is a 25 MHz +/- 50 ppm input signal. It should be
connected to a crystal, and the other end of the crystal should connect to XTAL2.
Crystal Two. Crystal Two is the output of an internal oscillator circuit used to drive a
crystal into oscillation.
