normal RAM accesses (see Section 5.6) and provide control
and status information for USB transactions.
Any Write to control register 0FH will enable the SL811HS full
features bit. This is an internal bit of the SL811HS that enables
additional features not supported by the SL11H. For SL11H
hardware backward compatibility, this register should not be
accessed.
Table 3-1. shows the memory map and register mapping of
both the SL11H and SL811HS in master/host mode. The
SL11H is shown for users upgrading to the SL811HS.
3.1
Table 3-1. SL811HS Master (Host) Register Summary
The registers in the SL811HS are divided into two major
groups. The first group is referred to as USB Control registers.
These registers enable and provide status for control of USB
transactions and data flow. The second group of registers
provides control and status for all other operations.

3.1.1
The following registers initialize to zero on power-up and reset:
All other registers power-up and reset in an unknown state and
should be initialized by firmware.
3.1.2
Communication and data flow on the USB bus uses the
SL811HS’ USB A-B Control Registers. The SL811HS can
communicate with any USB Device functions and any specific
endpoints via the USB-A or USB-B register sets.
The USB A-B Host Control Registers can be 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 Micro Controller when one of the
USB protocol transactions is completed. Table 3-1 and
Table 3-2 show the two sets of USB Host Control Registers,
the “A” set and “B” set. The two register sets allow for
overlapped operation. When one set of parameters is being
set up, the other can be transferring. On completion of a
transfer to an endpoint, the next operation will be controlled by
the other register set.
Note. On the SL11H, the USB-B set control registers are not
used. The USB-B register set can be 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.
