*) Only even values allowed. Odd values are automatically rounded.
As soon as during a count process an edge 0-1 is recognized at the
"Latch" input of a counter, the recent counter value is stored in the
according latch register.
You may access the latch register via LATCHVAL of the SFB 47.
A just in LATCHVAL loaded value remains after a STOP-RUN transition.
