AS3412 − Detailed Description

Slider Mode

Slider Mode is similar to Full Slider Mode with the only

difference that it is possible to use a push button (S3) to enable

and disable the Monitor Mode. Be aware that for Slider Mode

operation bit SLIDE_PWR_UP has to be set to ‘1’ and the SLIDER_

MON bit has to be set to ‘0’.

Figure 45:

Slider Mode

Slider Mode: The diagram shows the external connection of the switches and push button in slider mode.

The advantage of this mode compared to Full Slider Mode is the

automatic hold function of the Monitor Mode. Once the push

button S3 is pressed the device enters monitor mode. This mode

stays active until the user pushes the button again.
