请教:2812 ADC 问题

Other Parts Discussed in Thread: SPRC097

我现在ADC 是这么设置的:

1, ADC_CLK  = 25MHz,  (AdcRegs.ADCTRL3.bit.ADCCLKPS=3;AdcRegs.ADCTRL1.bit.CPS=0;  //内核时钟预分频);

2,AdcRegs.ADCTRL1.bit.ACQ_PS=2;  

3,AdcRegs.ADCTRL3.bit.SMODE_SEL=0;  // 顺序采样模式  (共6个通道顺序采样)

4,每3.25us 启动一次ADC;

我的问题是:

1,在这种配置下,ADC 转换时钟频率就是25MHz 吗?

2,3.25us 能完成6通道的转换并输出结果吗?是否太快了?

谢谢!
