Manchester encoding
Manchester encoding (also know as Biphase Code) is a synchronous clock encoding technique
used to encode the clock and data of a synchronous bit stream. In this technique, the actual
binary data to be transmitted are not sent as a sequence of logic 1's and 0's as in level encoded
way as in standard USART (known technically as Non Return to Zero (NRZ)). Instead, the bits
are translated into a slightly different format that has a number of advantages over using straight
binary encoding (i.e. NRZ).
Manchester encoding follows the rules:
If the original data is a Logic 1, the Manchester code is: 0 to 1 (upward transition at bit
center)
If the original data is a Logic 0, the Manchester code is: 1 to 0 (downward transition at bit
center)

19.3.3.1
Manchester frame
The USART supports Manchester encoded frames with the following characteristics:
One start bit Manchester encoded (logical ‘1’)
5, 6, 7, 8, 9, 13, 14,15,16,17 data bits in transmission or reception (MSB or LSB first)
The number of data bit in a frame is independently configurable in reception and
transmission mode.
One or Two stop bits (level encoded)
