System Clock

The system clock is driven by an oscillator. The following table defines the clock
frequencies for various configurations.

Real Time Clock Input

The RTC clock input is driven by 1MHz clock generated by the Control and Timers PLD.
This provides a fixed clock reference for the MC864xD PIC timers which software can use
as a known timing reference.
4.13.3

Local Bus Controller Clock Divisor

The Local Bus Controller (LBC) clock output is connected to the PLD but is not used by the
internal logic.
