Product data sheet
9.7 Host port for 16-bit extension of video data I/O (H port)
There are no empty cycles in the ancillary code and its data field. The data codes 00h
and FFh are suppressed (changed to 01h or FEh respectively) in the active video stream,
as well as in the VBI raw sample stream (VBI pass-through). Optionally, the number range
can be further limited.
Table 33:
[1]
The H port pins HPD can be used for extension of the data I/O paths to 16-bit.
The I port has functional priority. If I8_16[93h[6]] is set to logic 1 the output drivers of the
H port are enabled depending on the I port enable control. For I8_16 = 0, the HPD output
is disabled.
