NOTE: The programmable frequency divider can be set by applying the desired divide ratio, in binary, to the preset inputs. For example,
+V
CLOCK (f
DD
RESET
the maximum divide ratio of 255 may be obtained by applying a 1111 1111 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.
