求问28377D的adc采样频率等问题。



学习epwm转ADC时遇到一些疑问,看了datasheet后还是没弄明白,以例程adc_soc_epwm为例,发帖求问:

1、采用的模式是Up count,采样频率的计算公式是不是TPWM = (TBPRD + 1) x TTBCLK,FPWM = 1/ (TPWM)?TTBCLK是系统时钟的导数吗,还是经过分频以后的?怎么查看这个值?

2、AdcaRegs.ADCSOC0CTL.bit.ACQPS = acqps; //sample window is 100 SYSCLK cycles

这个设置的意思是不是采样时间为100个系统时钟?是不是这个时间乘以采样频率就是我的采样点数?

datasheet实在是没看明白,求大神帮小白解释解释,感激不尽。
