Pinout Specification of Serial Preprocessor for TriCore (AGBT/SGBT)

VREF is mandatory for a correct operation of the preprocessor.
Keep unused lanes unconnected!

The pinout of the 22-pin Samtec connector optionally includes the debug signals. The included target adapter (LA-3829) has a 16-pin JTAG connector and an AUTO26 connector to which you can connect the Debug Cable. Alternatively the Debug Cable can be connected to a separate debug connector on the target (JTAG, DAP or AUTO), in which case it is strongly recommended not to route the debug signals to the 22-pin trace connector.

Omitting the debug signals on the trace connector may improve signal quality. The debug signals are TCK, TMS, TRST-, TDI, TDO, RESET- and TRIG (user defined).

The preprocessor adapts to a 22-pin Samtec connector: (ERF8 series)

Recommendation is to place the even numbered pins at the PCB border side so the flex cable won't be twisted.

To connect to a target with a different connector, the following converters can be used.
The converter LA-3829 to connect to the 22-pin AGBT connector described here, is already included with your preprocessor.
