Serial Interface Considerations
7.2
The IMU-3000 supports I
secondary (accelerometer) interface.
7.3
The IMU-3000 accelerometer bus I/O logic levels are set to be either VDD or VLOGIC, as shown in the table
below.
VLOGIC may be set to be equal to VDD or to another voltage, such that at all times VLOGIC is ≤ VDD.
When AUX_VDDIO is set to 0 (its power-on-reset value), VLOGIC is the reference voltage for both the
microprocessor system bus and the accelerometer secondary bus, as shown in the figure of Section 8.2.1.
When AUX_VDDIO is set to 1, VLOGIC is the reference voltage for the microprocessor system bus and VDD
is the reference voltage for the accelerometer secondary bus, as shown in the figure of Section 8.2.2.

I/O Logic Levels vs. AUX_VDDIO bit
Notes:
AUX_VDDIO
1. CLKOUT has logic levels that are always referenced to VDD
2. The power-on-reset value for AUX_VDDIO is 0.
