ISOERREP Isochronous error endpoint. This is the endpoint number for the isochronous OUT endpoint
that has experienced a PID sequencing error and caused the ISO_ERR interrupt to assert.
The value in this register will always reflect the endpoint number for the last isochronous
OUT endpoint to experience a PID sequencing error (or 0x0 if no PID sequencing errors
have occurred). It is not cleared along with the USBISR[ISOERR] interrupt bit.
