AutoGen_973707 Posts: 2 Rating: (0)	Hello All, I have a 1212c CPU and currently i am working in a project that requires an encoder.I would like to ask for some guidance if there is a way to raise some interrupts when the encoder pulses reaches some values(i.e:500 pulses,then at 600 pulses, then at 1000 pulses etc). Any suggestions are welcome, thank you.
