DESCRIPTION
[7:0]
AVDET_STATUS
R
Display the detection status of each video or audio source
according
to
AVDET_EN,
VDET_MODE
and
ADET_MODE. The mapping of video/audio input to each
bit of the register is defined as below. The bits will be
cleared once the register is read by software except
VDET_MODE =3 or ADET_MODE=3.
Bit0: Video input CV_IN0.
Bit1: Video input CV_IN1.
Bit2: Video input CV_IN2.
Bit3: Video input CV_IN3.
Bit4: Audio input LINE_IN0.
Bit5: Audio input LINE_IN1.
Bit6: Audio input LINE_IN2.
Bit7: Audio input LINE_IN3.
0: Inactive. No event detected after the last access to this bit.
1: Active. An event is detected.
