Generating two PWM signals with a known phase relationship

Hello Friends !  ;D

With only a few hours to go before the end of the year, I am plagued by a doubt...is there a "simple" way to generate two PWM signals with a defined and programmable phase relationship between them using a PIC24FJ64GA004 without resorting to PIC24/DSPIC33 MCUs with high-speed PWM modules inside ?

You haven't described the end application, would software generated PWM be adequate (low prf)?

Hi John,

Two signals of identical frequency, less than 10 KHz and with 50% duty.
Theoretically it could be done with two suitably programmed timers and interrupt handling, I was wondering if it was possible at the HPWM level, also considering the achievable accuracy.
