9ANC_PKT_INS

Ancillary Packet Insertion Enable. When the FIFO is

configured for ancillary data insertion, set HIGH to

begin inserting ancillary data.

NOTE: Setting ANC_PKT_INS LOW will not

automatically disable ancillary data insertion (see

Ancillary Data Insertion on page 32).

R/W

8-7

FIFO_MODE[1:0]

FIFO Mode: These bits control which mode the

internal FIFO is operating in (see Table 3-2)

R/W

H_CONFIG

Horizontal sync timing output configuration. Set LOW

for active line blanking timing. Set HIGH for H

blanking based on the H bit setting of the TRS word.

See Figure 3-8 in HVF Timing Signal Inputs on page 35.

R/W

352M_CALCSMPTE 352M Calculation. When set LOW, the

GS9092A will automatically generate packet

information prior to insertion. When set HIGH, the

user must program the VIDEO_FORMAT registers with

the SMPTE 352M packet to be inserted.

R/W

–

352M_INSSMPTE 352M Packet Insertion. The IOPROC_EN pin

and SMPTE_BYPASS pin must also be set HIGH. Set

HIGH to disable.

NOTE: The user should disable Packet Insertion when

serializing SDTI signals.

R/W

–

ILLEGAL_REMAP

Illegal code re-mapping. Detection and correction of

illegal code words within the active picture area. The

IOPROC_EN pin and SMPTE_BYPASS pin must also be

set HIGH. Set HIGH to disable.

R/W

EDH_CRC_INS

Error Detection & Handling (EDH) Cyclical Redundancy

Check (CRC) error insertion. The GS9092A will

generate and insert EDH packets. The IOPROC_EN pin

and SMPTE_BYPASS pin must also be set HIGH. Set

HIGH to disable.

R/W

1ANC_CSUM_INS

Ancillary Data Checksum insertion. The IOPROC_EN

pin and SMPTE_BYPASS pin must also be set HIGH. Set

HIGH to disable.

R/W

0TRS_INS

Timing Reference Signal Insertion. Occurs only when

IOPROC_EN pin and SMPTE_BYPASS pin is HIGH. Set

HIGH to disable.
