RASING CONDITIONS
The status flags are grouped into four 8-bit registers.
The interrupt flag will only be cleared on a read access to
the status register in which the signal is located which
causedtheinterrupt.Thisimpliesthatitissufficienttoclear
the interrupt by reading only those registers which have
been enabled by their corresponding masks.
Priority: If a new trigger condition occurs at the SAME time
(clock) on which a status is being read, the flag will NOT
be cleared.

Video expansion port (X-port)
The expansion port is intended for transporting video
streams image data from other digital video circuits such
as MPEG encoder/decoder and video phone codec, to the
image port (I-port).
The expansion port consists of two groups of signals/pins:
8-bit data, I/O, regularly components video Y-C
B
-C
R
4 : 2 : 2, i.e. C
B
-Y-C
R
-Y, byte serial, exceptionally raw
video samples (e.g. ADC test). In input mode the data
bus can be extended to 16-bit by pins HPD7 to HPD0.
Clock, synchronization and auxiliary signals,
accompanying the data stream, I/O.
As output, these are direct copies of the decoder signals.
The data transfers through the expansion port represent a
single D1 port, with half duplex mode. The SAV and EAV
codes may be inserted optionally for data input (controlled
by bit XCODE[92H[3]]). The input/output direction is
switched for complete fields only.

as input normally a double pixel clock of up to 32 MHz or a
gated clock (clock gated with a qualifier)

if output, then decoder (HREF and VGATE) gate (see

I/O horizontal reference signal for the X-port:
as output: HREF or HS from the decoder (see Fig.30);
as input: a reference edge for horizontal input timing and a
polarity for input field ID detection can be defined
I/O vertical reference signal for the X-port:
as output: V123 or field ID from the decoder,
see Figs 28 and 29;
as input: a reference edge for vertical input timing and for
input field ID detection can be defined
