UD[7:0] USER DATA BITS
The user register is for arbitrary user data. It does not have any
influence on sensor operation. This data is transmitted during
Phase 2 of the state machine. For more information on trans-
mission format and timing, in particular depending on the
setting of MD bits, see the ADXL180 State Machine section.

The value of the RS bit may be transmitted during Phase 2, inde-
pendent of UD[7:0], depending on the selection of the MD bits.
BDE
Table 47. Bus Discharge Enable
BDE
The bus discharge enable (BDE) bit enables a discharge of the
bus voltage after a synchronization pulse is detected. If the BDE
bit is set, the ADXL180 changes the bus current (I
