11.2.5 USB Host Controller Blocks
11.2.5.1 AHB Slave
11.2.5.2 AHB Master
11.2.5.3 HCI Slave Block
A
H
B
This block allows access to the OHCI operational registers from/to the AHB via the HCI Bus.
This block enables the USB Host Controller to be an AHB Master peripheral and interfaces
with the HCI Master block via the HCI Bus.
The AHB Master includes a Data FIFO which will use a 44x37 bit Data FIFO. 32-bit data, 4-bit
HCI_MBeN[3:0] (byte lane enables) and HCI_MWBstOnN (burst on) make up the width of the
Data FIFO.
This block contains the OHCI operational registers, which are programmed by the Host
Controller Driver (HCD).
