2.5 CPU TO BUS FREQUENCY RATIO (JP12)
JP12 set the frequency ration between the Internal frequency of the CPU and the
External frequency (called the Bus clock) within the CPU. These must be set
together with the below jumpers CPU External (Bus) Frequency Selection.
2.6 CPU EXTERNAL (BUS) FREQUENCY
SELECTION (JP9, JP10, JP13)
JP9, JP10, JP13 tell the clock generator what frequency to send to the CPU. The Bus
clock times the Bus Ratio equals the CPU’s Internal frequency.
