and conducted noise.  
Used for mechanical button replacement. For example, wall  
switch.  
Reduces the radiated noise emission.  
Possible Noise Immunity levels are “Normal” and “High”.  
Flanking Sensor Suppression (FSS)  
LED ON Time  
Helps in distinguishing closely spaced buttons.  
Provides better visual feedback when a button is released and  
improves the design’s aesthetic value.  
Also used in situations with buttons having opposite functions.  
For example, an interface with two buttons for brightness  
control (UP or DOWN).  
The GPOx is driven low for a specified interval after the  
corresponding CSx button is released (see Figure 7).  
FSS action can be explained for following different scenarios:  
1. When only one button is touched, it is reported as ON. See  
Figure 5.  
When a button gets reset (refer to Button Auto Reset on page  
8), LED ON Time is not applied on the corresponding GPO.  
2. When more than one button is detected as ON and previously  
one of those buttons was touched, then the previously  
touched button is reported as ON. See Figure 6.  
Applicable to the GPO of the last button released.  
In Figure 8 on page 8, GPO0 goes high prematurely (prior to  
LED ON Time expiration) because CS1 button is released.  
Therefore, the LED ON Time counter is reset. Now, GPO1  
remains low for LED ON Time after releasing CS1.  
LED ON time can range from 0–2000 ms.  
LED ON time resolution is 20 ms.
