Data Field Error Flag — The data field received was not an interval of 8 bits. The USB Specification specifies
that the data field must be an integer number of bytes. If the data field was not an integer number of bytes, this
bit will be set.
0 The data field was an integer number of bytes
1 The data field was not an integer number of bytes
CRC16 Error Flag — The CRC16 failed. If set, the data packet was rejected due to a CRC16 error.
0 No CRC16 error detected
1 CRC16 error detected
CRC5 Error Flag — This bit will detect a CRC5 error in the token packets generated by the host. If set, the
token packet was rejected due to a CRC5 error.
0 No CRC5 error detected
1 CRC5 error detected, and the token packet was rejected.
PID Error Flag — The PID check failed.
0 No PID check error detected
1 PID check error detected
