The oscillator circuit is designed for use with crystals or ceramic
resonators. The oscillator circuit generates the crystal clock signal. The
crystal oscillator output signal passes through the clock doubler.
OSCXCLK is the output signal of the clock doubler. OSCXCLK is divided
by two before being passed on to the system integration module (SIM)
for bus clock generation.
