Figure 4. Programmable Cascaded Frequency Divider
Note: The programmable frequency divider can be set by applying the desired divide ratio, in BCD, to the preset inputs. For
example, the maximum divide ratio of 99 may be obtained by applying a 10011001 to the preset inputs P0 to P7. For this divide
operation, both counters should be configured in the count down mode. The divide ratio of zero is an undefined state and
should be avoided.
