LLC service request (continued)
Table 27. Bus Request
BIT(s)
NAME
DESCRIPTION
0
Start bit
Indicates the beginning of the transfer (always 1)
14
Request type
Indicates the type of bus request. See Table 26.
5
Request format
Indicates the packet format to be used for packet transmission. See Table 28.
69
Request speed
Indicates the speed at which the link sends the data to the PHY. See Table 29 for the encoding of this field.
10
Stop bit
Indicates the end of the transfer (always 0). If bit 6 is 0, then this bit may be omitted.
Table 28 shows the 1-bit request format field used in bus requests.
Table 28. Bus Request Format Encoding
LR5
DATA RATE
0
Link does not request either beta or legacy packet format for bus transmission
1
Link requests beta packet format for bus transmission
Table 29 shows the 4-bit request speed field used in bus requests.

NOTE:
The TSB41BA3A accepts a bus request with an invalid speed code and processes the bus request
normally. However, during packet transmission for such a request, the TSB41BA3A ignores any
data presented by the LLC and transmits a null packet.
For a read register request, the length of the LREQ bit stream is 10 bits as shown in Table 30.
