int triac_PhaseInitPWM(int channel, int pwm_level, int duty_
cycle, int options, unsigned long frequency);
Initializes a PWM channel for triac gate-signal power reduction.

0 = OK.
-1 = an invalid channel number is used.
-2 = an invalid duty cycle was requested.
-3 = frequency requested is out of range or invalid.
PWM_SPREAD sets pulse spreading. The duty cycle is spread over four separate pulses, and
PWM_OPENDRAIN sets the PWM output pin to be an open-drain output instead of a normal
0 sets the PWM for a normal push-pull logic output with no pulse spreading.

0 = sets PWM output low
1 = sets PWM output high.
