BTSEF: Bit Stuff Error Flag bit
1 = Packet rejected due to bit stuff error
0 = Packet accepted
BMXEF: Bus Matrix Error Flag bit
1 = The base address, of the BDT, or the address of an individual buffer pointed to by a BDT entry, is invalid.
0 = No address error
DMAEF: DMA Error Flag bit
1 = USB DMA error condition detected
0 = No DMA error
BTOEF: Bus Turnaround Time-Out Error Flag bit
1 = Bus turnaround time-out has occurred
0 = No bus turnaround time-out
DFN8EF: Data Field Size Error Flag bit
1 = Data field received is not an integral number of bytes
0 = Data field received is an integral number of bytes
CRC16EF: CRC16 Failure Flag bit
1 = Data packet rejected due to CRC16 error
0 = Data packet accepted

R/WC-0, HS
This type of error occurs when the module’s request for the DMA bus is not granted in time to service the
module’s demand for memory, resulting in an overflow or underflow condition, and/or the allocated buffer
size is not sufficient to store the received data packet causing it to be truncated.
This type of error occurs when more than 16-bit-times of Idle from the previous End-of-Packet (EOP)
has elapsed.
This type of error occurs when the module is transmitting or receiving data and the SOF counter has
reached zero.
