Table 18-15. ETPU_REDCR Field Descriptions
Bits Name Description
0 REN1 TCR1 resource
1
client/server operation enable. Enables or disables client/server operation
for the eTPU STAC interface. REN1 enables TCR1.
0 Server/client operation for resource 1 is disabled.
1 Server/client operation for resource 1 is enabled.
1 RSC1 TCR1 resource server/client assignment. Selects the eTPU data resource assignment to
be used as a server or client. RSC1 selects the functionality of TCR1. For server mode,
external plugging determines the unique server address assigned to each TCR. For a
client mode, the SRV1 field determines the server address to which the client listens.
0 Resource client operation.
1 Resource server operation.
2–3 — Reserved.
4–7 SERVER_ID
1
STAC bus address for TCR1 as a server.
For more information on the STAC interface, see Section Table 17-13., “STAC Client
Submodule Server Slot Assignment.
8–11 — Reserved.
12–15 SRV1
[0:3]
TCR1 resource server. Selects the address of the specific STAC Server the local TCR1 will
listen to when configured as a STAC client. For more information on the STAC interface,
refer to the eTPU reference manual.
16 REN2 TCR2 resource
1
client/server operation enable. Enables or disables client/server operation
for eTPU slave resources. REN2 enables TCR2 slave bus operations.
1 Server/client operation for resource 2 is enabled.
0 Server/client operation for resource 2 is disabled.
17 RSC2 TCR2
2
resource server/client assignment. Selects the eTPU data resource assignment to
be used as a server or client. RSC2 selects the functionality of TCR2. For server mode,
external plugging determines the unique server address assigned to each TCR. For a
client mode, the SRV2 field determines the Server address to which the client listens.
0 Resource Client operation.
1 Resource Server operation.
18–19 — Reserved.
