AS3412 − Detailed Description

Full Slider Mode

Full Slider Mode enables the AS3412 to be connected to two

slide switches for Power, ANC and Monitor Mode control. To

enable this operation mode both bits, SLIDE_PWR_UP and

SLIDER_MON, have to be set to ‘1’. The typical connection of the

slide switches is shown in Figure 43.

In Full Slider Mode the MODE/CSCL pin can detect three

different input levels to distinguish between different

operating modes: On, Off and Monitor mode. The timing

diagram with all relevant information is shown in Figure 44.
