OUT pipe.
The user has the possibility to run sequentially several logical pipes on the same physical pipe.
Before switching pipe, the user should save the pipe context (UPCFGn, UPCONn, UPSTAn,
and the pipe descriptor table).
After switching pipe, the user should restore the pipe context, current bank number, and the cur-
rent data toggle by using the UPCONn.INITDTGL and UPCONn.INITBK bits.
This error exists only for isochronous and interrupt pipes for both IN and OUT directions. It sets
the Errorflow Interrupt (ERRORFI) bit in UPSTAn, which triggers an PnINT interrupt if the Error-

bank has been affected.
This error exists only for isochronous IN pipes. It sets the CRC Error Interrupt bit (CRCERRI),
which triggers a PnINT interrupt if the CRC Error Interrupt Enable bit (UPCONn.CRCERRE) is
one.
