The EDH_FLAG register may be read by the host interface at any time during the
received frame except on the lines defined in SMPTE RP165 where these flags are
updated.
NOTE 1: By programming the ANC_TYPE1 register (005h) with the DID word for
EDH ancillary packets, the application layer may detect a high-to-low transition on
either the YANC or CANC output pin of the GS1560A/GS1561 to determine (a)
when EDH packets have been received by the device, and (b) when the
EDH_FLAG register can be read by the host interface. See
Ancillary Data
Detection and Indication on page 48
for more information on ancillary data
detection and indication.
NOTE 2: The bits of the EDH_FLAG register are sticky and will not be cleared by
a read operation. If the GS1560A/GS1561 is decoding a source containing EDH
packets, where EDH flags may be set, and the source is replaced by one without
EDH packets, the EDH_FLAG register will not be cleared.
NOTE 3: The GS1560A/GS1561 will detect EDH flags, but will not update the flags
if an EDH CRC error is detected. Gennum's GS1532 Multi-Rate Serializer allows
the host to individually set EDH flags.
