Host port for 16-bit extension of video data I/O (H port)
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.

Basic input and output timing diagrams I port
and X port
9.8.1
I PORT OUTPUT TIMING
The following diagrams illustrate the output timing via the
I port. IGPH and IGPV are logic 1 active gate signals.
If reference pulses are programmed, these pulses are
generated on the rising edge of the logic 1 active gates.
Valid data is accompanied by the output data qualifier on
pin IDQ. In addition invalid cycles are marked with output
code 00H.
The IDQ output pin may be defined to be a gated clock
output signal (ICLK AND internal IDQ).
9.8.2
X PORT INPUT TIMING
At the X port the input timing requirements are the same as
those for the I port output. But different to those below:
It is not necessary to mark invalid cycles with a 00H
code
No constraints on the input qualifier (can be a random
pattern)
XCLK may be a gated clock (XCLK AND external XDQ).
Remark: All timings illustrated in Figs 38 to 44 are given
for an uninterrupted output stream (no handshake with the
external hardware).
