Register Description
The Device n Address register holds the device address assigned by the host. This register initializes to the default address 0 at
reset but must be updated by firmware when the host assigns a new address. Only USB data sent to the address contained in
this register will be responded to, all others are ignored.
Address (Bits [6:0])
The Address field contains the USB address of the device assigned by the host.
Reserved
All reserved bits must be written as ‘0’.

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
