Register Description
The Device n Status Register provides status information for
device operation. Pending interrupts can be cleared by writing
a ‘1’ to the corresponding bit. This register can be accessed
by the HPI interface.
VBUS Interrupt Flag (Bit 15)
The VBUS Interrupt Flag bit indicates the status of the OTG
VBUS interrupt (only for Port 1A). When enabled this interrupt
triggers on both the rising and falling edge of VBUS at 4.4V.
This bit is only available for Device 1 and is a reserved bit in
Device 2.
1: Interrupt triggered
0: Interrupt did not trigger
ID Interrupt Flag (Bit 14)
The ID Interrupt Flag bit indicates the status of the OTG ID
interrupt (only for Port 1A). When enabled this interrupt
triggers on both the rising and falling edge of the OTG ID pin.
This bit is only available for Device 1 and is a reserved bit in
Device 2.
1: Interrupt triggered
0: Interrupt did not trigger
SOF/EOP Interrupt Flag (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 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.
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:
1: Interrupt triggered
0: Interrupt did not trigger
