Square wave generation using CCP Modules on 16f747

Hi,

I am looking to generate three seperate square waves using the pwm modules on the 16f747 pic chip. This isn't really to hard by setting the duty cycle of each square wave to 50% and the desired period using a specific PR2value. However, I would like the three square waves to be 120 Degrees out of phase. This is to control a three phase inverter bridge using the six step voltage source method. Can anyone please tell me the best way of doing this?

Thanks

Anyone got any ideas? Its abit urgent!

Three square waves from CCP modules of 16f747, same duty cycle and same time period. Just they are 120 degrees out of phase with respect to one another.
