4.13.1 System Clock
The system clock is driven by an oscillator. The following table defines the clock frequency.
4.13.2 Real Time Clock Input
The RTC clock input is driven by 1 MHz clock generated by the Control and Timers PLD. This
provides a fixed clock reference for the MPC8548E 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.
