7.3.1 DID Control
Address 36Ah
Default 000h
7 6 5 4 3 2 1 0
Unscaled field 1 DID Unscaled field 0 DID
15 14 13 12 11 10 9 8
Scaled field 1 DID Scaled field 0 DID
This register controls the value of the EAV DID bytes for scaled and unscaled data. The value for each
field can be independently set, allowing identification of both which field is being processed and whether
the data comes from the scaled or unscaled channel.
7.3.2 Misc Control
Address 36Bh
Default 0Ch
7 6 5 4 3 2 1 0
Clock rate Clock OE Clock edge
15 14 13 12 11 10 9 8
Scaled blank data
Scaled blank data:
When no active scaled data is available, this value is output during the active video region.
Clock rate:
This register controls various clock modes. Since this register is modified by the device during normal operation, the clock rate bits
should not be modified by the user.
Clock OE:
This register controls various clock modes. Since this register is modified by the device during normal operation, the clock rate bits
should not be modified by the user.
Clock edge:
This register controls various clock modes. Since this register is modified by the device during normal operation, the clock rate bits
should not be modified by the user.
7.3.3 Interleave Field Control 1
Address 36Dh
Default 0h
7 6 5 4 3 2 1 0
End pixel count[7:0]
15 14 13 12 11 10 9 8
Field count Reserved Blank timing End pixel count[9:8]
End pixel count:
Pixel count at which the frame status is updated. Do not change this value.
Blank timing:
0: No timing signals are generated for blank fields.
1: H, V, and F timing generated for blank fields based on unscaled video timing sequences
Field count:
Number of output fields in field interleaved sequence
