MIL-STD-1553 Manchester Encoding

MIL-STD-1553 is a DOD Military (MIL) Standard (STD), which defines both the Mechanical, Electrical, and Functional characteristics.
MIL-STD-1553 uses Manchester II Bi-Phase L bit encoding.
Manchester Encoding translates a '1' into a low to high transition [01], and a '0' is translated into a high to low transition [10].
Also called Biphase Code. Other types of Data Encoding.

Manchester code: A code in which the data and clock signals are combined to form a single self synchronizing data stream, each encoded bit contains a transition at the midpoint of a bit period.
The direction of transition determines whether the bit is a 0 or a 1, and the first half is the true bit true bit value. This contrasts with non-return-to zero.

With NRZ encoding a 1 is sent as a high and a 0 is sent as a low.
