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).
At the X port the input timing requirements are the same as those for the I port output. But
different to those below:
Remark: All timings illustrated in
output stream (no handshake with the external hardware).
