Enhanced Time Processing Unit (eTPU2)
TCR2 value used on matches and captures. See Section 29.3.5, Time Bases.
29.2.6.4 ETPUREDCR - eTPU STAC Configuration Register
This register configures the eTPU STAC bus operation as a STAC Server/Client module (see
Section 29.3.5.3, STAC Interface).

REN1,2 — TCR1/2 Resource¹ Client/Server Operation Enable Bits
These bits enable or disable Client/Server operation to eTPU STAC resources. REN1 enables TCR1
and REN2 enables TCR2 STAC bus operations.
1 = Server/Client Operation for resource 1/2 is enabled.
0 = Server/Client Operation for resource 1/2 is disabled.
RSC1,2 — TCR1/2 Resource Server/Client Assignment Bits
These bits select the eTPU data resource assignment to be used as Servers or Clients. RSC1 selects the
functionality of TCR1 and 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 SRV1
and SRV2 fields determine 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.
NOTE
RSC1,2 must not be changed when the respective REN1,2 bit is asserted.
SERVER_ID1,2 — STAC Ids 1,2
STAC Server Ids (read-only plug values) used for TCR1 and TCR2, respectively, when STAC servers.
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).
