This error only exists for isochronous OUT endpoints. It sets the CRC Error Interrupt (USBHS_DEVEPTISRx.CRCERRI) bit, which triggers a PEP_x interrupt if the CRC Error Interrupt Enable (USBHS_DEVEPTIMRx.CRCERRE) bit is one.
A CRC error can occur during the OUT stage if the USBHS detects a corrupted received packet. The OUT packet is stored in the bank as if no CRC error had occurred (USBHS_DEVEPTISRx.RXOUTI is set).
