Is a PWM phase duration set with OCR1A a reliable way to communicate values to other Arduinos?

I am working on communicating 4 switch states across multiple Arduinos using only one pin. It must be as fast as conceivably possible. Currently I have a master Arduino reading all 4 switches (multiplexing) and encoding them as 4-bit values: 0001 =…
