Individual bits can only be cleared by writing a ‘1’ to the bit position as part of a word write operation on the
entire register. Using Boolean instructions or bitwise operations to write to a single bit position will cause
all set bits at the moment of the write to become cleared.
Unimplemented: Read as ‘0’
BTSEF: Bit Stuff Error Flag bit
1 = Bit stuff error has been detected
0 = No bit stuff error
Unimplemented: Read as ‘0’
DMAEF: DMA Error Flag bit
1 = A 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 was not an integral number of bytes
0 = Data field was an integral number of bytes
CRC16EF: CRC16 Failure Flag bit
1 = CRC16 failed
0 = CRC16 passed
For Device mode:
CRC5EF: CRC5 Host Error Flag bit
1 = Token packet rejected due to CRC5 error
0 = Token packet accepted (no CRC5 error)
For Host mode:
EOFEF: End-Of-Frame Error Flag bit
1 = End-Of-Frame error has occurred
0 = End-Of-Frame interrupt disabled
PIDEF: PID Check Failure Flag bit
1 = PID check failed
0 = PID check passed. Individual bits can only be cleared by writing a ‘1’ to the bit position as part of
the number of received bytes. The received data is truncated.
