CRC Error
SW
SW
write data to CPU
SW
This error exists only for isochronous IN pipes. It raises the CRC Error interrupt (CRCERRI),
what triggers a PXINT interrupt if CRCERRE = 1.
A CRC error can occur during IN stage if the USB controller detects a corrupted received packet.
The IN packet is stored in the bank as if no CRC error had occurred (RXINI is raised).
