Operation of Serialized IRQ
A cycle operation of serialized IRQ starts with Start Frame and fin-
ishes with Stop Frame. There are two modes of operation :
Continuous (Idle) mode and Quiet (Active) mode. The next opera-
tion mode is determined by monitoring the stop frame pulse width.
qTiming of serialized IRQ cycle
Figure 54 shows the timing diagram of serialized IRQ cycle.
(1) Start Frame
The Start Frame is detected when the SERIRQ line remains “L” in
4 to 8 clocks.

(2) IRQ/Data Frame
Each IRQ/Data Frame is three clocks. When the IRQi (i = 0, 1, x)
request is “0”, then the SERIRQ line is driven to “L” during the
Sample phase (1st clock) of the corresponding IRQ/Data frame,
to “H” during the Recovery phase (2nd clock), to tri-state during
the Turn-around phase (3rd clock). When the IRQi request is “1”,
then the SERIRQ line is tri-state in all phases (3 clocks period).
(3) Stop Frame
The Stop Frame is detected when the SERIRQ line remains “L” in
2 or 3 clocks. The next operation mode is Quiet mode when the
pulse width of “L” is 2 clocks. The next operation mode is the
Continuous mode when the pulse width is 3 clocks.
