See “Clickctrl Register” on page 19.
The sensor generates a click detection. The host must read the b7 bit of the status register or
the b1 bit of the general navigation register.
The click function is composed of an array of a few pixels and a processing unit. The typical click
slice frequency is 90 Hz. A programmable divider is implemented to modify this frequency in the
control registers (CLICKFREQ).
This function is performed by the controller, allowing better flexibility. It detects a succession of
two clicks.
