SL811HS
Document #: 38-08008 Rev. *A
Page 9 of 29
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.
5.1
The following registers initialize to zero on power-up and reset:
USB-A/USB-B Host Control Register [00H, 08H] bit 0 only
Control Register 1 [05H]
USB Address Register [07H]
Current Data Set/Hardware Revision/SOF Counter LOW Register [0EH]
All other registers power-up and reset in an unknown state and should be initialized by firmware.
Register Values on Power-up and Reset
5.2
Communication and data flow on the USB uses the SL811HS
’
s USB A-B Control Registers. The SL811HS can communicate with
any USB Device functions and any specific endpoints via the USBA or USBB register sets.
The USB A-B Host Control Registers can be used in a Ping-Pong arrangement to manage traffic on the USB. The USB Host
Control Register also provides a means to interrupt an external CPU or Micro Controller when one of the USB protocol transac-
tions is completed. The table above shows 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 is 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.
