多谢版主的解答!
但是有没有关于这两个滤波器更多的资料呢?
digital Filter的设置中有这样一个位域
Filter Length
The digital filter configuration is valid in all digital pin muxing modes. Configures the maximum size of the
glitches, in clock cycles, that the digital filter absorbs for the enabled digital filters. Glitches that are longer than this register setting will pass through the digital filter, and glitches that are equal to or less than this register setting are filtered. 这个用了一个词“glitches”是说误差?
另外PFE的描述中提到
Refer to the device data sheet for filter characteristics.
但是data sheet中哪个地方说的是这个滤波器的参数呢?
