I'm wondering if it is possible, during a timer interrupt service, to attach "slave" pins to the OCnA and OCnB timer outputs, such that I could have an extra pin doing whatever OCnA is doing (or the opposite) and an extra pin doing whatever OCnB is doing (or the opposite). I need OCnA and OCnB to behave differently, but I need two of each of them (and inverted)! Thoughts?
For more background, I am trying to adapt something like this: http://interface.khm.de/index.php/lab/experiments/arduino-dds-sinewave-generator/ ...to do this: http://arduino.cc/forum/index.php/topic,116089.0.html
I'm thinking I can vary the phase between OCnA and OCnB slightly to acheive the delay that I need to avoid short circuiting, and then if I can duplicate them, I can control all 4 switches.
