Error, or OUT Exception Error. In addition, the NAK Interrupt
Enable bit in the Device n Endpoint Control register can also be
set so that NAK responses trigger this interrupt.
1: Enable EP1 Transaction Done interrupt
0: Disable EP1 Transaction Done interrupt
EP0 Interrupt Enable (Bit 0)
The EP0 Interrupt Enable bit enables or disables endpoint zero
(EP0) Transaction Done interrupt. An EPx Transaction Done
interrupt triggers when any of the following responses or events
occur in a transaction for the device’s supplied Endpoint:
send/receive ACK, send STALL, Timeout occurs, IN Exception
Error, or OUT Exception Error. In addition, the NAK Interrupt
Enable bit in the Device n Endpoint Control register can also be
set so that NAK responses trigger this interrupt.
1: Enable EP0 Transaction Done interrupt
0: Disable EP0 Transaction Done interrupt
Reserved
Write all reserved bits with ’0’.
Device n Address Register [W]
■ Device 1 Address Register 0xC08E
■ Device 2 Address Register 0xC0AE
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 gets a respond—all others are ignored.
Address (Bits [6:0])
The Address field contains the USB address of the device
assigned by the host.
Reserved
Write all reserved bits with ’0’.
Device n Status Register [R/W]
■ Device 1 Status Register 0xC090
■ Device 2 Status Register 0xC0B0
