Figure 22-29. Example of an OUT Pipe with two Data Banks and a Bank Switching Delay
This error exists only for isochronous IN pipes. It set the CRC Error Interrupt (CRCERRI) bit,
what triggers a PnINT interrupt if then the CRC Error Interrupt Enable (CRCERRE) bit in
UPCONn is one.
A CRC error can occur during IN stage if the USBB detects a corrupted received packet. The IN
packet is stored in the bank as if no CRC error had occurred (RXINI is set).
See the structure of the USB host interrupt system on
There are two kinds of host interrupts: processing, i.e. their generation is part of the normal pro-
cessing, and exception, i.e. errors (not related to CPU exceptions).
The processing host global interrupts are:
• The Device Connection Interrupt (DCONNI)
• The Device Disconnection Interrupt (DDISCI)
• The USB Reset Sent Interrupt (RSTI)
• The Downstream Resume Sent Interrupt (RSMEDI)
• The Upstream Resume Received Interrupt (RXRSMI)
• The Host Start of Frame Interrupt (HSOFI)
• The Host Wake-Up Interrupt (HWUPI)
• The Pipe n Interrupt (PnINT)
• The DMA Channel n Interrupt (DMAnINT)
There is no exception host global interrupt.
The processing host pipe interrupts are:
• The Received IN Data Interrupt (RXINI)
