To request access to the bus, to read or write a Phy register, or to control arbitration acceleration, the
TSB12LV32 sends a serial bit stream on the LREQ terminal as shown in Figure 8

The length of the stream will vary depending on the type of request as shown in Table 8

Regardless of the type of request, a start-bit of 1 is required at the beginning of the stream, and a stop-bit
of 0 is required at the end of the stream. The second through fourth bits of the request stream indicate the
type of the request. In the descriptions below, bit 0 is the most significant and is transmitted first in the request
bit stream. The LREQ terminal is normally low.
Encoding for the request type is shown in Table 8

NAME
DESCRIPTION
000
ImmReq
Immediate bus request. Upon detection of idle, the Phy takes control of the bus immediately
without arbitration.
001
IsoReq
Isochronous bus request. Upon detection of idle, the Phy arbitrates for the bus without waiting
for a subaction gap.
010
PriReq
Priority bus request. The Phy arbitrates for the bus after a subaction gap, ignores the fair
protocol.
011
FairReq
Fair bus request. The Phy arbitrates for the bus after a subaction gap, follows the fair protocol.
100
RdReg
The Phy returns the specified register contents through a status transfer.
101
WrReg
Write to the specified register.
110
AccelCtl
Enable or disable asynchronous arbitration acceleration.
111
Reserved
Reserved.
For a bus request the length of the LREQ bit stream is 7 or 8 bits as shown in Table 8

0
Start Bit
Indicates the beginning of the transfer (always 1).

Request Type
Indicates the type of bus request (see Table 8

6
Request Speed
Indicates the speed at which the Phy will send the data for this request (see Table 8
–
6)
for the encoding of this field.
7
Stop Bit
Indicates the end of the transfer (always 0). If bit 6 is 0, this bit may be omitted.
The 3-bit request speed field used in bus requests is shown in Table 8
