1.5.4 Illegal Code Re-mapping
When LIMIT_ON bit 4 of Host Interface register 008h is set
HIGH, input video words between 000-003 are re-mapped
to 004, and values between 3FC-3FF are re-mapped to
3FB. Valid only when the EXT_SEL bit 3 of Host Interface
register 000h is set HIGH.
1.5.5 Input Blanking
When VBLK_INS bit 3 of Host Interface register 008h is set
HIGH, the input video vertical blanking will be set to 040h for
the Luma channel and 200h for the Chroma channel.
When HBLK_INS bit 2 of Host Interface register 008h is set
HIGH, the input video horizontal blanking will be set to 040h
for the Luma channel and 200h for the Chroma channel. The
TRS, line number and CRC words will also be set to blanking
values.
The blanking function is performed at the output of the
GS1503 video data stream. If the HBLK_INS bit is set HIGH,
any multiplexed audio will be replaced with blanking codes.
1.5.6 Line Number Insertion
When LN_INS bit 1 of Host Interface register 008h is set
HIGH, the GS1503 will insert line numbers into the video
data stream. When set LOW, existing line numbers will
remain in the output video stream.
When EXT_SEL bit 3 of Host Interface register 001h is set
HIGH, line numbers will be inserted based on the timing of
EXTH and EXTF input signals.
