Carrier enable and configuratoin
| CHOPPER2_EN | When set, carrier0 function is enabled. When cleared, carrier0 is bypassed |
| CHOPPER2_PRESCALE | PWM carrier0 clock (PC_clk) prescale value. Period of PC_clk = period of PWM_clk * (PWM_CARRIER0_PRESCALE + 1) |
| CHOPPER2_DUTY | carrier duty selection. Duty = PWM_CARRIER0_DUTY / 8 |
| CHOPPER2_OSHTWTH | width of the fist pulse in number of periods of the carrier |
| CHOPPER2_OUT_INVERT | when set, invert the output of PWM2A and PWM2B for this submodule |
| CHOPPER2_IN_INVERT | when set, invert the input of PWM2A and PWM2B for this submodule |
