– Manchester (also known as Bi-Phase)
The desired line coding scheme can be selected via bit field ’SC(2:0)’ in register CCR0H.
3.2.13.1 NRZ and NRZI Encoding
NRZ: The signal level corresponds to the value of the data bit. By programming bit ’DIV’
(CCR1L
NRZI: A logical ‘0’ is indicated by a transition and a logical ‘1’ by no transition at the
beginning of the bit cell.

3.2.13.2 FM0 and FM1 Encoding
FM0: An edge occurs at the beginning of every bit cell. A logical ‘0’ has an additional
edge in the center of the bit cell, whereas a logical ‘1’ has none. The transmit clock
precedes the receive clock by 90 ° .
FM1: An edge occurs at the beginning of every bit cell. A logical ‘1’ has an additional
edge in the center of the bit cell, a logical ‘0’ has none. The transmit clock precedes the
receive clock by 90 ° .
