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,
19 write bit or reset pulse.
21 The default baud-rate for reset and presence detection is 9600 and for
22 a 1-Wire read or write operation 115200. In case the actual baud-rate
24 to generate the 1-Wire timing patterns.

32 reset-bps:
35 The baud rate for the 1-Wire reset and presence detect.
37 write-0-bps:
40 The baud rate for the 1-Wire write-0 cycle.
42 write-1-bps:
45 The baud rate for the 1-Wire write-1 and read cycle.
