(Bit 9)
The SOF/EOP Interrupt Flag bit indicates if the SOF/EOP
received interrupt has triggered.
1:
Interrupt triggered
0:
Interrupt did not trigger
Reset Interrupt Flag
(Bit 8)
The Reset Interrupt Flag bit indicates if the USB Reset
Detected interrupt has triggered.
1:
Interrupt triggered
0:
Interrupt did not trigger
EP7 Interrupt Flag
(Bit 7)
The EP7 Interrupt Flag bit indicates if the endpoint seven
(EP7) Transaction Done interrupt has triggered. An EPx
Transaction Done interrupt triggers when any of the following
responses or events occur in a transaction for the devices
given EP: send/receive ACK, send STALL, Time-out occurs,
IN Exception Error, or OUT Exception Error. In addition, if the
NAK Interrupt Enable bit in the Device n Endpoint Control
register is set, this interrupt also triggers when the device
NAKs host requests.
1:
Interrupt triggered
0:
Interrupt did not trigger
EP6 Interrupt Flag
(Bit 6)
The EP6 Interrupt Flag bit indicates if the endpoint six (EP6)
Transaction Done interrupt has triggered. An EPx Transaction
Done interrupt triggers when any of the following responses or
events occur in a transaction for the devices given EP:
send/receive ACK, send STALL, Time-out occurs, IN
Exception Error, or OUT Exception Error. In addition, if the
NAK Interrupt Enable bit in the Device n Endpoint Control
register is set, this interrupt also triggers when the device
NAKs host requests.
1:
Interrupt triggered
0:
Interrupt did not trigger
EP5 Interrupt Flag
(Bit 5)
The EP5 Interrupt Flag bit indicates if the endpoint five (EP5)
Transaction Done interrupt has triggered. An EPx Transaction
Done interrupt triggers when any of the following responses or
events occur in a transaction for the devices given EP:
send/receive ACK, send STALL, Time-out occurs, IN
Exception Error, or OUT Exception Error. In addition, if the
NAK Interrupt Enable bit in the Device n Endpoint Control
register is set, this interrupt also triggers when the device
NAKs host requests.
1:
Interrupt triggered
0:
Interrupt did not trigger
EP4 Interrupt Flag
(Bit 4)
The EP4 Interrupt Flag bit indicates if the endpoint four (EP4)
Transaction Done interrupt has triggered. An EPx Transaction
Done interrupt triggers when any of the following responses or
events occur in a transaction for the devices given EP:
send/receive ACK, send STALL, Time-out occurs, IN
Exception Error, or OUT Exception Error. In addition, if the
NAK Interrupt Enable bit in the Device n Endpoint Control
register is set, this interrupt also triggers when the device
NAKs host requests.
1:
Interrupt triggered
0:

EP3 Interrupt Flag
(Bit 3)
The EP3 Interrupt Flag bit indicates if the endpoint three (EP3)
Transaction Done interrupt has triggered. An EPx Transaction
Done interrupt triggers when any of the following responses or
events occur in a transaction for the devices given EP:
send/receive ACK, send STALL, Time-out occurs, IN
Exception Error, or OUT Exception Error. In addition, if the
NAK Interrupt Enable bit in the Device n Endpoint Control
register is set, this interrupt also triggers when the device
NAKs host requests.
1:
Interrupt triggered
0:
Interrupt did not trigger
EP2 Interrupt Flag
(Bit 2)
The EP2 Interrupt Flag bit indicates if the endpoint two (EP2)
Transaction Done interrupt has triggered. An EPx Transaction
Done interrupt triggers when any of the following responses or
events occur in a transaction for the devices given EP:
send/receive ACK, send STALL, Time-out occurs, IN
Exception Error, or OUT Exception Error. In addition, if the
NAK Interrupt Enable bit in the Device n Endpoint Control
register is set, this interrupt also triggers when the device
NAKs host requests.
1:
Interrupt triggered
0:
Interrupt did not trigger
EP1 Interrupt Flag
(Bit 1)
The EP1 Interrupt Flag bit indicates if the endpoint one (EP1)
Transaction Done interrupt has triggered. An EPx Transaction
Done interrupt triggers when any of the following responses or
events occur in a transaction for the devices given EP:
send/receive ACK, send STALL, Time-out occurs, IN
Exception Error, or OUT Exception Error. In addition, if the
NAK Interrupt Enable bit in the Device n Endpoint Control
register is set, this interrupt also triggers when the device
NAKs host requests.
1:
Interrupt triggered
0:
Interrupt did not trigger
EP0 Interrupt Flag
(Bit 0)
The EP0 Interrupt Flag bit indicates if the endpoint zero (EP0)
Transaction Done interrupt has triggered. An EPx Transaction
Done interrupt triggers when any of the following responses or
events occur in a transaction for the devices given EP:
send/receive ACK, send STALL, Time-out occurs, IN
Exception Error, or OUT Exception Error. In addition, if the
