6.11.7.7 EVENTS_REPORTRDY

Address offset: 0x104

Non-null report ready

Event generated when REPORTPER number of samples has been accumulated in the ACC register and the

content of the ACC register is not equal to 0. (Thus, this event is only generated if a motion is detected

since the previous clearing of the ACC register).

6.11.7.9 EVENTS_DBLRDY

Address offset: 0x10C

Double displacement(s) detected

Event generated when REPORTPER number of samples has been accumulated and the content of the

ACCDBL register is not equal to 0. (Thus, this event is only generated if a double transition is detected

since the previous clearing of the ACCDBL register).
