TIMER FUNCTION
The V55PI timer unit can be used as an interval timer, free-running timer and event counter. It is also possible to
manipulate P7 as a real-time output port, synchronized with interrupt requests generated by the timer. The normal timer
function and real-time output port function are described here.
