ST_XL_0

1. This bit must be set to 0 for the correct operation of the device.

Table 71. CTRL10 register description

EMB_FUNC_DEBUG

Enables debug mode for the embedded functions.

(0: disabled; 1: enabled)

AH_QVAR_SW

Swaps the input electrodes of Qvar. Default value: 0

(0: swap disabled; 1: swap enabled)

XL_ST_OFFSET

To be used during the accelerometer self-test procedure. When this bit is set to 1, only the offset is

measured; when set to 0, the offset plus the self-test signal is measured. The final self-test output is

obtained by the difference between the outputs with XL_ST_OFFSET 1 and 0.

CTRL_STATUS

Table 73. CTRL_STATUS register description

FSM_WR_CTRL_STATUS

This flag indicates the current controller of the device configuration registers. This flag must be

used as an acknowledge flag when the value of the FSM_WR_CTRL_EN bit in the

FUNC_CFG_ACCESS (01h) register is changed. Default value: 0

(0: all registers and configurations are writable from the standard interface;

1: some registers and configurations are under FSM control and are in read-only mode from the

standard interface).
