Data Sheet
116
CGMVCLK is the clock output from the VCO.
CGMOUT is the clock output of the CGM. This signal goes to the SIM,
which generates the MCU clocks. CGMOUT is a 50 percent duty cycle
clock running at twice the bus frequency. CGMOUT is software
programmable to be either the oscillator output, CGMXCLK, divided by
two or the divided VCO clock, CGMPCLK, divided by two.
CGMINT is the interrupt signal generated by the PLL lock detector.
The following registers control and monitor operation of the CGM:
