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 device’s
given EP: send/receive ACK, send STALL, Timeout 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 device’s given EP:
send/receive ACK, send STALL, Timeout 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 device’s given EP:
send/receive ACK, send STALL, Timeout 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 device’s given EP:
send/receive ACK, send STALL, Timeout 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
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 device’s given EP:
send/receive ACK, send STALL, Timeout 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 device’s given EP:
send/receive ACK, send STALL, Timeout 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 device’s given EP:
send/receive ACK, send STALL, Timeout 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)

Done interrupt triggers when any of the following responses or
events occur in a transaction for the device’s given EP:
send/receive ACK, send STALL, Timeout 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
