你好，帮我看看，请问如下图配置，生成是pwm波的周期实测为什么是25K，而不是50k
还有个问题，pwm时钟频率是不是默认100MHZ？
试一下这么改：
EPWM_setTimeBasePeriod(myEPWM1_BASE, 4000); EPWM_setClockPrescaler(myEPWM1_BASE, EPWM_CLOCK_DIVIDER_2, EPWM_HSCLOCK_DIVIDER_2);
PWM时钟复位的时候默认是100MHz。
实测3.125k，能否帮我讲解下，3.125k是如何配置出来的？
TBCLK = EPWMCLK/(highSpeedPrescaler * pre-scaler)
按照这个公式，时基 = 100/(2*2) = 25 M
周期 = 25M/4000 = 6.25k,为何实测是3.125k
在帮我看看
