7 title: UART 1-Wire Bus
10 - Christoph Winklhofer <cj.winklhofer@gmail.com>
13 UART 1-wire bus. Utilizes the UART interface via the Serial Device Bus
14 to create the 1-Wire timing patterns.
16 The UART peripheral must support full-duplex and operate in open-drain
18 baud-rate and transmitted byte, which corresponds to a 1-Wire read bit,
