14.1 Contents
14.2 Introduction
The miscellaneous register exists to hold various system control bits. It
is located at address $0021.
14.3 Miscellaneous Control Register
SPEED — CPU Speed Select
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.
