28377D ePWM 触发ADC 问题-TI中文支持网

在我的应用里，我使用PWM1/2/3 来配置电机所需要的6 路 PWM，使用EPWM4 来触发三路ADCa/b/c，按理来说三个ADC a / b / c 应该是完全等价的，但奇怪的是，当我把6 路 PWM 发出来之后，跑一会，随后发生某一个ADC 工作彻底停摆了（三个中断服务程序ISR，总有那么一两个就彻底进不去了），我想知道是否我的ADC 配置是否有遗漏的，我的ADC 配置如下，烦请有相关经验的同学帮我诊断一下，在此拜谢了！！

}
else
{
acqps = ADC_acqps_16BIT; // 320ns resolution is 16-bit
}
