Noise Filter
PS025011-1010
Architecture
Operation
A noise filter circuit is included which filters noise on a digital input signal (such as UART
Receive Data) before the data is sampled by the block. This is likely to be a requirement
for protocols with a noisy environment.
The noise filter contains the following features:
