AT90USB82/162
Underflow
CRC Error
The KILLBK bit is used to kill the last “written” bank. The best way to manage this abort is to per-
form the following operations:
Table 20-1.
An underflow can occur during IN stage if the host attempts to read a bank which is empty. In
this situation, the UNDERFI interrupt is triggered.
An underflow can also occur during OUT stage if the host send a packet while the banks are
already full. Typically, he CPU is not fast enough. The packet is lost.
It is not possible to have underflow error during OUT stage, in the CPU side, since the CPU
should read only if the bank is ready to give data (RXOUTI=1 or RWAL=1)
A CRC error can occur during OUT stage if the USB controller detects a bad received packet. In
this situation, the STALLEDI interrupt is triggered. This does not prevent the RXOUTI interrupt
from being triggered.
In Control, Isochronous, Bulk or Interrupt Endpoint, an overflow can occur during OUT stage, if
the host attempts to write in a bank that is too small for the packet. In this situation, the OVERFI
interrupt is triggered (if enabled). The packet is hacknowledged and the RXOUTI interrupt is also
triggered (if enabled). The bank is filled with the first bytes of the packet.
• In a control transaction: ZLP data OUT received during a IN stage,
• In an isochronous IN transaction: ZLP data OUT received on the OUT endpoint during a IN
• ...
stage on the IN endpoint

Abort is based on the fact
that no banks are busy,
meaning that nothing has to
