DESCRIPTION ON FUNCTION AND OPERATION
1. Programmable counter
When the MODE INPUT (Pin 22) is set to "L" level (or opened), the programmable counter becomes
swallow system.
The system consists of a 7bit swallow counter, 11bit programmable counter and a prescaler logic
which change-over the number of divisions of the 2-module prescaler connected to the outside.

_" P/P+1 _ (A) - (N)
D0 _ De D7 _ D17
0 Total number of divisions can be determined by the following formula
Number of divisions = (P+1)-A+P-(N -A)
= N-P+A Where, N>A
o The prescaler used requires to be the number of divisions of P+1 when the PSC terminal is in
"L" level and of P when it is in "H" level.
It The input for setting the number of divisions of the programmable counter consists of 18bits,
but it should be cared that it changes by the number of divisions P of the prescaler used.
