peripheral device drives the IRQSER high. During the Turn-around phase, the peripheral device left
the IRQSER tri-stated.
The IRQ/Data Frame has a number of specific order, as shown in Table 14-2.
14.3 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.
