PWM1A和PWM1B配置位死区互补形式输出，调整CMPA的值，改变Duty;
PWM1A和PWM1B是否都能实现互补形式的高精度输出？
实际测试问题情况是这样的：PWM1A的下降沿会按照CMPAHR调整值进行变化，但是PWM1B的上升沿不对对应的变化。
DB没块的配置如下：
HRPWM配置如下：
//
// Hi-res PWM
// MEP control on both edges.
//
HRPWM_setMEPEdgeSelect(base1, HRPWM_CHANNEL_A, HRPWM_MEP_CTRL_FALLING_EDGE);
HRPWM_setCounterCompareShadowLoadEvent(base1, HRPWM_CHANNEL_A, HRPWM_LOAD_ON_CNTR_ZERO_PERIOD);
HRPWM_setMEPControlMode(base1, HRPWM_CHANNEL_A, HRPWM_MEP_DUTY_PERIOD_CTRL);
HRPWM_setDeadbandMEPEdgeSelect(base1, HRPWM_DB_MEP_CTRL_RED_FED);
HRPWM_setRisingEdgeDelayLoadMode(base1, HRPWM_LOAD_ON_CNTR_ZERO_PERIOD);
HRPWM_setFallingEdgeDelayLoadMode(base1, HRPWM_LOAD_ON_CNTR_ZERO_PERIOD);
//
// Enable autoconversion
//
HRPWM_enableAutoConversion(base1);
//
// Turn on high-resolution period control.
//
HRPWM_enablePeriodControl(base1);
