7.2.1 AUX_VDDIO = 0<br />
The figure below shows logic levels and voltage connections for AUX_VDDIO = 0. Note: Actual configuration<br />
will depend on the type of 3 rd -party accelerometer used.<br />

Notes:<br />
1. AUX_VDDIO is bit 7 in Register 24, and determines the IO voltage levels of AUX_DA and AUX_CL (0 = set<br />
output levels relative to VLOGIC)<br />
2. CLKOUT is always referenced to VDD<br />
3. Other <strong>ITG</strong>-<strong>3050</strong> logic IO are always referenced to VLOGIC<br />
I/O Levels and Connections for AUX_VDDIO = 0<br />
