Interrupts
• Global interrupts
• Pipe interrupts
A CRC error can occur during the IN stage if the USBC detects a corrupted packet. The IN
packet will remain stored in the bank and RXINI will be set.
The user can check the Pn_CTR_STA_BK0/1.CRCERR bit in the pipe descriptor to see which
current bank has been affected.
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:
There is no exception host global interrupt.
The processing host pipe interrupts are:
The exception host pipe 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 Wakeup Interrupt (HWUPI)
• The Pipe n Interrupt (PnINT)
• The Received IN Data Interrupt (RXINI)
• The Transmitted OUT Data Interrupt (TXOUTI)
• The Transmitted SETUP Interrupt (TXSTPI)
• The Number of Busy Banks (NBUSYBK) interrupt
• The Errorflow Interrupt (ERRORFI)
• The Pipe Error Interrupt (PERRI)
• The NAKed Interrupt (NAKEDI)
• The Received STALLed Interrupt (RXSTALLDI)
• The CRC Error Interrupt (CRCERRI)
