OSCXCLK is the crystal oscillator output signal. It runs at the full speed
of the crystal (f
circuit. The duty cycle of OSCXCLK is unknown and may depend on the
crystal and other external factors. Also, the frequency and amplitude of
OSCXCLK can be unstable at start-up.
OSCRCLK is the buffered version of OSCXCLK. It runs at the full speed
of the crystal (f
DCLK1 is the clock output of the CGM. This signal goes to the sync
processor, which generates the display clocks. DCLK1 is software
programmable to be either the oscillator output (OSCXCLK) or the VCO
clock (CGMVCLK).
CGMINT is the interrupt signal generated by the PLL lock detector.
The following registers control and monitor operation of the CGM:
