out an error on source B the count will be equal to

the Load Value.

+1. If the count is equal to 9,999 when the transition

occurs count will be 1 after transition.
If Function is a Down Counter:
Whenever a prescribed clock transition occurs with-

out an error on Source A the count will decrement by

-1. If the count is equal to 0 when the transition oc-

curs the count will be 9,999 after transition.
