2.2 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.
