SERVER_ID1—STAC Id 1
STAC Server Id (read-only plug values) used for TCR1 when STAC servers.
12-15
SRV1—TCR1 Resource Server
These bits select the address of the specific STAC Server to which the local TCR1 listens when configured
as a STAC Client. SRV1 selects the STAC Server of TCR1.
16
REN2—TCR2 Resource
This bit enables or disables Client/Server operation to eTPU STAC resources. REN2 enables TCR2 STAC
bus operations.
1: Server/Client Operation for resource 2 is enabled.
0: Server/Client Operation for resource 2 is disabled.
17
RSC2—TCR2 Resource Server/Client Assignment Bits
This bit selects the eTPU data resource assignment to be used as Servers or Clients. 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.
1: Resource Server operation.
0: Resource Client operation.
Note: When TCR1 or TCR2 is configured as a STAC Bus Client (REN2 = 1, RSC2 = 0) the eTPU Angle
Clock hardware cannot be used.
RSC2 must not be changed when the respective REN1,2 bit is asserted.

Reserved
20-23
SERVER_ID2—STAC Id 2
STAC Server Id (read-only plug values) used for TCR2 when STAC servers.
24-27
Reserved
28-31
SRV2—TCR2 Resource Server
These bits select the address of the specific STAC Server to which the local TCR2 listens when configured
as a STAC Client. SRV2 selects the STAC Server of TCR2.
1
resource identifies any parameter that changes along the time and can be exported / imported from other device.
In eTPU context, a resource can be TCR1 or TCR2 (either Time or Angle values).
2
resource identifies any parameter that changes along the time and can be exported / imported from other device.
In eTPU context, a resource can be TCR1 or TCR2 (either Time or Angle values).
