15 The HDQ/1-Wire module of TI OMAP2430/3430 platforms implement the hardware
17 Semiconductor 1-Wire protocols. These protocols use a single wire for
18 communication between the master (HDQ/1-Wire controller) and the slave

21 A typical application of the HDQ/1-Wire module is the communication with battery
