15.3. Three-out-of-Six Encoding
Three out of six encoding is similar to Manchester encoding. In Three-out-of-Six encoding a nibble is
encoded as a six-bit symbol. Four nibbles are encoded as 24-bits (three bytes).
Two bytes of data to be encoded are written to ENC0M and ENC0L. The MODE bit is set to 1 for Three-
out-of-Six encoding. Setting the ENC bit will initiate encoding.
After encoding, the three encoded bytes are in ENC2-0.
