Write:
This control bit, when set, selects an additional divide-by-eight after
the already divide-by-five from the oscillator clock to the internal bus
clock. This makes the internal CPU clock a divide-by-40 from the
oscillator input.
When clear, the internal bus clock is a divide-by-five from the
oscillator input. Reset clears this bit.
