1) Written values into those register addresses are ignored
2) Bit12=1 means BD is in BD_Normal (read) or shall go to BD_Normal (write).
4.2.5 bus signal interface
The basic bus driver has neither a BD_Sleep mode nor a remote wake up functionality. The receiver recognizes all
3 states of the bus lines (Data_0, Data_1 and Idle).
The RxD output becomes high, if an idle state is detected at the bus lines.
The RxD output becomes high, if an Data_1 state is detected at the bus lines.
The RxD output becomes low, if an Data_0 state is detected at the bus lines.
4.2.5.1 Receiver
The receiver circuit is responsible for receiving the bus signals, but also for biasing the bus lines. Figure 9 shows
the principle schematic of the input behaviour of the receiver. Besides definitions of transient parameters of the
receiver behavior from idle to active and vice versa are shown. The numerical values are defined in chapter 3.4.1.
uBus is the differential bus voltage.
