RS485 ( SN65HVD3082E ) : Manchester (or biphase) encoding circuit

Hello Satoshi-san,

Manchester encoding is often implemented in software. For example, rather than driving an output pin high for a full bit duration, an MCU may use a routine to drive it high for half a bit period and then low for the remaining half of the bit period. Similarly, a low level could be represented by a low "first half" and high "second half" of the bit. It is also possible to implement the same thing in hardware. A simple implementation would be to combine a serial data signal with its accompanying clock signal using an XOR function.
