手册3273页 55.2.3.1 Glitch Filter
Because the quadrature decoder logic must sense signal transitions, the signal inputs are
first run through a glitch filter. This glitch filter has a digital delay line, which samples
multiple time points on the signal and verifies a stable new signal state, before outputting
this new signal state to the internal quadrature decoder logic. To adapt to a variety of
signal bandwidths, the sample rate of this delay line is programmable. 你看看对你是否有用 nxp定时器方面该有不错的功底 |
