Description
Vertical blanking enable. When set HIGH, the
output video vertical blanking will be set to 040h
for the Luma channel and 200h for the Chroma
channel.
Horizontal blanking enable. When set HIGH, the
output video horizontal blanking, including TRS,
line numbers and line CRC words, will be set to
040h for the Luma channel and 200h for the
Chroma channel.
NOTE: If blanking of line numbers and TRS words
is required, LN_INS and TRS_INS must be set
LOW.
Line insertion enable. When set HIGH, the
GS1503B will insert line numbers into the video
data stream. When set LOW, existing line
numbers will remain in the output video stream.
TRS insertion enable. When set HIGH, the
GS1503B will insert TRS codes into the video
data stream. When set LOW, existing TRS codes
will remain in the output video stream.
Audio input format (external pin/register)
configuration select. When set LOW, the audio
input format is configured via the AM[1:0] pins.
When set HIGH, the audio input format is
configured via the "AM[1:0]" bits.
Ch7/8 audio input signal detection. When set
HIGH, an audio signal has been detected at the
AIN7/8 input pin.
Ch5/6 audio input signal detection. When set
HIGH, an audio signal has been detected at the
AIN5/6 input pin.
Ch3/4 audio input signal detection. When set
HIGH, an audio signal has been detected at the
AIN3/4 input pin.
Ch1/2 audio input signal detection. When set
HIGH, an audio signal has been detected at the
AIN1/2 input pin.
Not used.
Audio input format select. See
when "AM_SEL" is HIGH.
Ch7/8 audio Channel Status CRC insertion. When
set HIGH, the Ch7/8 audio input Channel Status
CRC is re-calculated before being multiplexed
into the Audio Data Packet. Valid only when
AES/EBU audio input format is selected.
