@/count-looped
Stores a number which gets incremented on each `INC` pulse.
TRIGpulse
Triggers a single increment.
INCnumber
Value to add on each increment. Use a negative value (e.g. -1) to make decrements.
BEGINnumber
First step to be activated
ENDnumber
Last Step to be activated, you may use WIDTH to calculate this , alternatively!
WIDTHnumber
Number of steps to be activated after BEGIN, you may use END to determine this , alternatively!
RSTpulse
Resets the accumulated value to zero.
OUTnumber
The accumulated value. (range 1-16)
