14.6 OPERATION IN STL

Utilizing the three counters and the reference or interrupt input can also be done in STL. The settings
are made in the END routine.
If the settings must be used immediately, operating system routines can be called. This is done with a
pointer in the operating system. The pointer refers to the address of the routine.
Actual values and preset values of the counter sit at operating system addresses. The counter initializa-
tion is done with three registers (control register, mode register and initialization register).
