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

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.
