This program illustrates the use of the Dithering mode of the SMPS dsPIC
* devices. It uses a sequential tuning of the FRC oscillator to produce a
* +/- 3 dither in the frequency.
* The dithering mode is useful in reducing the effective EMI produced by
* high frequency switching of semiconductor switches used in switched mode
* power supply applications.
* In this program, PWM1 and PWM2 are configured in the complementary mode
* and produce constant duty cycles. The dither mode will cause the PWM
* signals to jitter about the factory calibrated frequency.
* All timings are calculated assuming 30 MIPS operation.-This program illustrates the use of the Dithering mode of the SMPS dsPIC
