Table 64. CTRL7 register description

AH_QVAR_EN

Enables the analog hub and Qvar chain. When this bit is set to 1, the analog hub Qvar buffers are

connected to the AH1/QVAR1 and AH2/QVAR2 pins. Before setting this bit to 1, the accelerometer

and gyroscope sensors have to be configured in power-down mode. Default value: 0

(0: disabled; 1: enabled)

INT2_DRDY_AH_QVAR

Analog hub and Qvar data-ready interrupt on the INT2 pin. Default value: 0

(0: disabled; 1: enabled)

AH_QVAR_C_ZIN_[1:0]

Configures the equivalent input impedance of the analog hub and Qvar buffers.

(00: 2.4 GΩ (default);

01: 730 MΩ;

10: 300 MΩ;

11: 235 MΩ)

AH_QVAR1_EN

Enables the AH1/QVAR1 pin. Default value: 0

(0: disabled; 1: enabled)

AH_QVAR2_EN

Enables the AH2/QVAR2 pin. Default value: 0

(0: disabled; 1: enabled)

LPF1_G_EN

Enables the gyroscope digital LPF1 filter
