Device n Address Register [W]

■ Device 1 Address Register 0xC08E

■ Device 2 Address Register 0xC0AE

Figure 36. Device n Address Register

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’.

Device n Status Register [R/W]

■ Device 1 Status Register 0xC090

■ Device 2 Status Register 0xC0B0

Figure 37. Device n Status Register

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 4.4 V. 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
