Figure 5 Audio Response
The audio output can be muted with the MUTE_EN
(Reg14h[7]) bit and the output can also be replaced by
an internally generated 1KHz tone whenever the RFI
has a RF signal input.
3.3 Auto Seek (CCA)
In receive mode, the QN8075 can automatically tune to
stations with good signal quality. The auto seek
function is referred to CCA (Clear Channel
Assessment).
