Description
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.
Not used.
Audio input format select. See
when "AM_SEL" is HIGH.
Not used.
Demultiplex Mode select. When set HIGH, the
GS1503B requires a 48kHz word clock input at
WCINA and WCINB. This word clock must be
synchronous to the word clock used to embed
the audio data. The embedded clock information
in the audio data packet will be ignored.
See
NOTE: The status of the DEC_MODE external pin
is not updated in this register. The value
programmed in this register is logical OR'd with
the DEC_MODE external pin setting.
Ch5-8 audio sample clock error. When set HIGH,
the GS1503B is unable to recover the audio clock
phase data in the embedded audio data packet
for audio channels 5 to 8. See
Ch1-4 audio sample clock error. When set HIGH,
the GS1503B is unable to recover the audio clock
phase data in the embedded audio data packet
for audio channels 1 to 4. See

5.11.
