User can set BRKAEVEN (TIMERx_PWMBRKCTL[17:16]) for PWMx_CH0 output state and
BRKAODD (TIMERx_PWMBRKCTL[19:18]) for PWMx_CH1 output state when PWM brake event
happened. There are two brake detector sources, edge detect brake source and level detect
brake source when brake event happened. Figure 6.17-17 shows the brake event block diagram
for PWMx_CH0 and PWMx_CH1.
