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
Figure 21-5. Character Transmit
The characters are sent by writing in the Transmit Holding Register (THR). The transmitter
reports two status bits in the Channel Status Register (CSR): TXRDY (Transmitter Ready),
which indicates that THR is empty and TXEMPTY, which indicates that all the characters written
in THR have been processed. When the current character processing is completed, the last
character written in THR is transferred into the Shift Register of the transmitter and THR
becomes empty, thus TXRDY rises.
Both TXRDY and TXEMPTY bits are low when the transmitter is disabled. Writing a character in
THR while TXRDY is low has no effect and the written character is lost.

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.
