CGM Registers
PLL Control
Register
15-cgm
MOTOROLA
Address:
Three registers control and monitor operation of the CGM:
The PLL control register contains the interrupt enable and flag bits, the
on/off switch, and the base clock selector bit.

This read/write bit enables the PLL to generate a CPU interrupt
request when the LOCK bit toggles, setting the PLL flag, PLLF. When
the AUTO bit in the PLL bandwidth control register (PBWC) is clear,
PLLIE cannot be written and reads as logic 0. Reset clears the PLLIE
bit.
