10.5.1.3
The USB Error Interrupt Status Register (UEIR) con-
tains bits for each of the error sources within the USB.
Each of these bits are enabled by their respective
error enable bits (UEIE). The result is OR’ed together
and sent to the ERROR bit of the UIR register. Once

BTS_ERR: A bit stuff error has been detected
OWN_ERR: This bit is set if the USB is processing a token and the OWN bit within the BDT is equal to 0
WRT_ERR: Write Error
A write by the MCU to the USB Buffer Descriptor Table or Buffer area was unsuccessful. This error occurs
when the MCU attempts to write to the same location that is currently being written to by the SIE.
BTO_ERR: This bit is set if a bus turnaround time-out error has occurred. This USB uses a bus turnaround

as soon as the error condition is detected. Thus, the
interrupt will typically not correspond with the end of a
