Tap detection

The device can be configured to send an interrupt signal on a dedicated pin when “clicked”

in any direction (see Figure 4).

A more advanced feature also allows the detection of a “double click” event, with a

programmable time interval between the first and second click, to enable a “mouse button-

like” functionality.

These functions can be fully programmed. For additional information, please contact your

local STMicroelectronics sales office.
