Description
Overrun/Underrun*
0: No error
1: An error occurred
Indicates that a data buffer error is the source of
error notification with the NRDY interrupt for the pipe
in which isochronous transfer is being performed.
For details, see tables 23.8 and 23.9.
Receive Data Error*
0: No error
1: An error occurred
Indicates that the source of error notification with the
NRDY interrupt for the pipe in which isochronous
transfer is being performed is a packet error.
For details, see tables 23.8 and 23.9.
Reserved
These bits are always read as 0. The write value
