28379D 中BISS-C的时钟频率能由PWM4改成PWM其他通道吗?

Other Parts Discussed in Thread: CONTROLSUITE

如题,1、bissc_configEPWM4();能换成bissc_configEPWM10()或者其他的吗?

2、PM_bissc_setFreq(BISSC_FREQ_DIVIDER);  // set BISSC_FREQ_DIVIDER to 25 for 2MHz

例程里面这个函数打不开具体定义,只看到PWM4的管脚定义了,不知道具体是怎么来控制EPWM4的PWM周期,不知道BISS-C和EPWM4怎么联系到一起的

3、void bissc_init(void)

{
EALLOW;
CpuSysRegs.PCLKCR2.bit.EPWM3  = 1;
CpuSysRegs.PCLKCR2.bit.EPWM4  = 1;
EDIS;

............

}

这个EPWM3又起到什么作用,下面的程序只看到初始化EPWM4的管脚了
