HB IsoFlush
CRC error
Interrupts
•Global interrupts
•Endpoint interrupts
filled by the CPU (three expected) for the current micro-frame. Then, the HBISOINERRI interrupt
is generated at the end of the micro-frame. Note that an UNDERFI interrupt is also generated
(with an automatic zero-length-packet), except in the case of a missing IN token.
This error exists only for high-bandwidth isochronous IN endpoints.
At the end of the micro-frame, if at least one packet has been sent to the host, if there is missing
IN token during this micro-frame, the bank(s) destined to this micro-frame is/are flushed out to
ensure a good data synchronization between the host and the device.
For instance, if NBTRANS is three (three transactions per micro-frame), if only the first IN token
(among 3) is well received by the USBB, then the two last banks will be discarded.
This error exists only for isochronous OUT endpoints. It set the CRC Error Interrupt (CRCERRI)
bit in UESTAn, what triggers an EPnINT interrupt if the CRC Error Interrupt Enable (CRCERRE)
bit is one.
A CRC error can occur during OUT stage if the USBB detects a corrupted received packet. The
OUT packet is stored in the bank as if no CRC error had occurred (RXOUTI is set).
See the structure of the USB device interrupt system on
There are two kinds of device interrupts: processing, i.e. their generation is part of the normal
processing, and exception, i.e. errors (not related to CPU exceptions).
The processing device global interrupts are:
The exception device global interrupts are:
The processing device endpoint interrupts are:
• The Suspend (SUSP) interrupt
• The Start of Frame (SOF) interrupt with no frame number CRC error (the Frame Number
• The Micro Start of Frame (MSOF) interrupt with no CRC error.
• The End of Reset (EORST) interrupt
• The Wake-Up (WAKEUP) interrupt
• The End of Resume (EORSM) interrupt
• The Upstream Resume (UPRSM) interrupt
• The Endpoint n (EPnINT) interrupt
• The DMA Channel n (DMAnINT) interrupt
• The Start of Frame (SOF) interrupt with a frame number CRC error (FNCERR is one)
• The Micro Start of Frame (MSOF) interrupt with a CRC error
• The Transmitted IN Data Interrupt (TXINI)
CRC Error (FNCERR) bit in the Device Frame Number (UDFNUM) register is zero)
