Preliminary Data Sheet
Input sync controller (ISCM/ISCS)
internal signal VTSEQM is generated. This signal level is high (VTSEQM=1), if at least
the last to fields were identical. Due to the fixed storage places of the fields in the internal
memory block, this information is necessary for the scan rate conversion processing
("Output sync controller (OSCM/S)" on page 77, it is recommended in case of
VCRMODEM=0 to choose an adaptive operation mode).
The OPDELM I²C Bus parameter is used to adjust the outgoing V-Sync VOUT in relation
to the incoming delayed V-Sync VINM. In case of SSC and MUP mode the
recommended default value should not be changed.
