8.3.4
Hub Endpoint 0 Data Register – HDR0
8.3.5
Function Endpoint 0..3 Data Register – FDR0..3
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 hard-
ware and is not accessible by the firmware. The bits in this register when read by the host will
be:
Bit 7,6 – Reserved
These bits are reserved in the AT43USB325 and will read as zero.
Bit 5 – P5 SC: Port 5 Status Change
Bit 4 – P4 SC: Port 4 Status Change
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
