Receiver
Description
The receive filter is responsible for conditioning the received signal RxS for clock
recovery and clock decoding.
The Manchester decoder obtains the data from the filtered received signal.
The clock recovery function obtains the CLK1 clock from the filtered received
signal.
The data decoder scans the filtered received signal at the recovered received clock
rate RxC (positive edge) and passes on the scanned value weighted with the
polarity information transferred by the decoder state machine (POL=1 or POL=0)
as the received signal RxD.
