15.2. Manchester Decoding
Two bytes of Manchester data are written to ENC0M and ENC0L sfrs. Then the DEC bit is set to initiate
decoding. After decoding the READY bit will be set. If the data is not a valid encoded Manchester data, the
ERROR bit will be set, and the output will be all FFs.
The encoding and decoding process should be symmetric. Data can be written to the ENC0L sfr, then
encoded, then decoding will give the original data.
