3313D–USB–04/06
Hub Endpoint 0 Data Register – HDR0
Function Endpoint 0..2 Data Register – FDR0..2
This register is used to read data from or to write data to the Hub Endpoint 0 FIFO.
Bit 7..0 – FDAT7..0: FIFO Data
Hub endpoint 1 has a single byte data register instead of a FIFO. This data register contains
the hub and port status change bitmap. This data register is automatically updated by the USB
hardware and is not accessible by the firmware. The bits in this register when read by the host
will be:
Bit 7...4 – Reserved
These bits are reserved in the AT43USB326 and will read as zero.
Bit 3 – P3 SC: Port 3 Status Change
Bit 2 – P2 SC: Port 2 Status Change
Bit 1 – P1 SC: Port 1 Status Change
Bit 0 – H SC: Hub Status Change
