ITL0BufferDone and ITL0BufferFull bits will be cleared automatically. This also
applies to the ITL1 buffer because ITL0 and ITL1 are Ping-Pong structured buffers. To
recover from this state, a power-on reset or software reset will have to be applied.

Time domain behavior
In example 1 (
Figure 21
), the CPU is fast enough to read back and download a
scenario before the next interrupt. Note that on the ISO interrupt of frame N:
The ISO packet for frame N
+
1 will be written
The AT packet for frame N
+
1 will be written.
In example 2 (
Figure 22
), the microprocessor is still busy transferring the AT data
when the ISO interrupt of the next frame (N
+
1) is raised. As a result, there will be no
AT traffic in frame N
+
1. The HC does not raise an AT interrupt in frame N
+
1. The
AT part is simply postponed until frame N
+
2. On the AT N
+
2 interrupt, the transfer
mechanism is back to the normal operation. This simple mechanism ensures, among
other things, that Control transfers are not dropped systematically from the USB in
case of an overloaded microprocessor.
In example 3 (
Figure 23
), the ISO part is still being written while the Start of Frame
(SOF) of the next frame has occurred. This will result in undefined behavior for the
ISO data on the USB bus in frame N
+
1 (depending on whether the exact timing data
is corrupted or not). The HC should not raise an AT interrupt in frame N
+
1.
