Manchester Encoder
encoded based on biphase Manchester II format. To enable this mode, set the MAN field in the
MR register to 1. Depending on polarity configuration, a logic level (zero or one), is transmitted
as a coded signal one-to-zero or zero-to-one. Thus, a transition always occurs at the midpoint of
When the Manchester encoder is in use, characters transmitted through the USART are
each bit time. It consumes more bandwidth than the original NRZ signal (2x) but the receiver has
more error control since the expected input must show a change at the center of a bit cell. An
example of Manchester encoded sequence is: the byte 0xB1 or 10110001 encodes to 10 01 10
10 01 01 01 10, assuming the default polarity of the encoder.
scheme.

The Manchester encoded character can also be encapsulated by adding both a configurable
preamble and a start frame delimiter pattern. Depending on the configuration, the preamble is a
training sequence, composed of a pre-defined pattern with a programmable length from 1 to 15
bit times. If the preamble length is set to 0, the preamble waveform is not generated prior to any
character. The preamble pattern is chosen among the following sequences: ALL_ONE,
ALL_ZERO, ONE_ZERO or ZERO_ONE, writing the field TX_PP in the MAN register, the field
TX_PL is used to configure the preamble length.
patterns. To improve flexibility, the encoding scheme can be configured using the TX_MPOL
field in the MAN register. If the TX_MPOL field is set to zero (default), a logic zero is encoded
with a zero-to-one transition and a logic one is encoded with a one-to-zero transition. If the
TX_MPOL field is set to one, a logic one is encoded with a one-to-zero transition and a logic
zero is encoded with a zero-to-one transition.
