5.5.3 Stop Frame
After all IRQ/Data Frames have completed, the host controller will terminate SERIRQ by
a Stop frame. Only the host controller can initiate the Stop frame by driving SERIRQ low for 2 or 3
clocks. If the Stop Frame is low for 2 clocks, the next SERIRQ cycle's Sample mode is the Quiet
mode. If the Stop Frame is low for 3 clocks, the next SERIRQ cycle's Sample mode is the
Continuous mode.
