Latch Input 1 Enable or

is set to 1, but the coun-
ter value will not latch
even when the signal is
input.
After the counter value is
latched, Latch Input 1 Com-
pleted Flag or Latch Input 2
Completed Flag changes to 1.
Until this flag is cleared, you
cannot perform another latch.
Change Latch Input 1 Enable or Latch Input 2

When one of these bits changes to 0, the Latch Input
1 Completed Flag or Latch Input 2 Completed Flag
will also change to 0 and the system is again ready
for latching.
