Int value servo control and program flow

The rectifying bridge may verywell result in 120hz however it is isolated and is only used for the opto-coupler signaling.

but this affects the frequency measurement

@geeknhard

I was referring to the C++ being converted to binary and the length of instructions for attaching vs switching interrupts

i think you're missing the point. noInterrupt/interrupt() are the proper way to temporarily disable interrupts around "critical sections"
