SL811HS
Document #: 38-08008 Rev. *A
Page 10 of 29
Bit 3 is reserved for future usage.
The SL811HS uses bit 5 to enable transfer of a data packet after a SOF packet is transmitted. When this bit set
“
1,
”
the next
enabled packet will be sent after next SOF. If set =
“
0
”
the next packet is sent immediately if the SIE is free.
The SL811HS automatically generates preamble packets when bit 7 is set. This bit is only used to send packets to a low-speed
device through a hub. To communicate to a full speed device, this bit is set to zero. For example, when SL811HS communicates
to a low-speed device via the HUB:
—
SL811HS SIE should set to operate at 48 MHz, i.e., bit 5 of register 05H should be set =
“
0.
”
—
Bit 6 of register 0FH should be set =
“
0,
”
set correct polarity of DATA+ and DATA
–
state for Full Speed.
—
Bit 7, Preamble Bit, should be set =
“
1
”
in Host Control register.
When SL811HS communicates directly to low-speed device:
—
SL811HS. Bit 5 of register 05H should be set =
“
1.
”
—
Bit 6 of register 0FH should be set =
“
1,
”
DATA+ and DATA
–
polarity for low speed.
—
The state of bit 7 is ignored in this mode.

Bit Name
Function
0
Arm
Allows enabled transfers when set =
“
1.
”
Cleared to
“
0
”
when transfer is complete.
1
Enable
When set =
“
1
”
allows transfers to this endpoint. When set
“
0
”
USB transactions are ignored.
If Enable =
“
1
”
and Arm = '0' the endpoint will return NAKs to USB transmissions.
2
Direction
When set =
“
1
”
transmit to Host. When
“
0
”
receive from Host.
3
Reserved
4
ISO
When set to
“
1
”
allows Isochronous mode for this endpoint.
5
SOF
“
1
”
= Synchronize with the SOF transfer
6
Data Toggle Bit
“
0
”
if DATA0,
“
1
”
if DATA1.
7
Preamble
If set =
“
1
”
a preamble token is transmitted prior to transfer of low-speed packet. If set =
“
0,
”
preamble generation is disabled.
