Note:  
When a click is detected, the information is placed in the b7 bit of the status register and  
in the b1 bit of the general navigation register. The reading of the status register initial-  
izes the b7 bit but does not initialize the b1 bit of the general navigation register. The host  
must carefully correlate the two bits.
