Stop Character

The stop character is a framing character that the UART

generates to signal the end of a message. It is transmit-

ted as an unencoded 54h, but it is still a DC-balanced

character.

Manchester Encoding

Each data byte is transmitted as two separate nibbles

(four bits) that are Manchester-encoded. For each data

bit, the first bit represents the information and the

second bit is its complement. The parity is even so its

value should always result in an even number of high

bits. Since the data is Manchester-encoded and there are

twoSTOPbits,theparitybitfordatacharacters(butnot

framingcharacters)shouldalwaysbezero.
