6 / 32 page SL811HS Document 38-08008 Rev. *F Page 6 of 32 USB Control Registers Communication and data flow on the USB bus uses the SL811HS’ USB A-B Control registers. The SL811HS communi- cates with any USB Device function and any specific endpoint via the USB-A or USB-B register sets. The USB A-B Host Control registers are used in an overlapped configuration to manage traffic on the USB bus. The USB Host Control register also provides a means to interrupt an external CPU or microcontroller when one of the USB protocol transac- tions is completed. Table 1 and Table 2 show the two sets of USB Host Control registers, the ’A’ set and ’B’ set. The two register sets allow for overlapping operation. When one set of param- eters is being set up, the other is transferring. On completion of a transfer to an endpoint, the next operation is controlled by the other register set. Note The USB-B register set is used only when SL811HS mode is enabled by initializing register 0FH. The SL811HS USB Host Control has two groups of five registers each which map in the SL811HS memory space. These registers are defined in the following tables. Table 2.
