General Operation
Figure 8-1 shows a block diagram of the Manchester encoder/decoder. Logic ow of the hardware
operation of the encoder and decoder are shown in Figure 8-2 and Figure 8-3 respectively.
8.2.1
Encoder
The Manchester Encoder is used to convert data from NRZ format to Manchester Code format;
and output onto the ENCOOUT pin.
