7.3 Stop Frame
After all IRQ/Data Frames have completed , the host controller will terminate IRQSER by a Stop
frame. Only the host controller can initiate the Stop frame by driving IRQSER low for 2 or 3 clocks. If
the Stop Frame is low for 2 clocks, the next IRQSER cycle's Sample mode is the Quiet mode. If the
Stop Frame is low for 3 clocks, the next IRQSER cycle's Sample mode is the Continuous mode.
7.4 Reset and Initialization
After MR reset, IRQSER Slaves are put into the Continuous(Idle) mode. The Host Controller is
responsible for starting the initial IRQSER Cycle to collect system's IRQ/Data default values. The
system then follows with the Continuous/Quiet mode protocol (Stop Frame pulse width) for
subsequent IRQSER cycles. It's the Host Controller's responsibility to provide the default values to
8259's and other system logic before the first IRQSER cycle is performed. For IRQSER system
suspend, insertion, or removal application, the Host controller should be programmed into
Continuous(Idle) mode first. This is to guarantee IRQSER bus in the Idle state before the system
configuration changes.
