Hardware Description
4.5
Debug Interface
The ETK-S6.0 features a AUD-II debugging interface connector CON5 (Samtec
16 pin).

This connector can be used to attach debug tools (e.g. Lauterbach or Renesas
debugger for Renesas SH72513FCC).
By using the AUD-II interface for serial ETK connection, it is not available for
debugging tools anymore. Therefore a feedthrough for a second debugger inter-
face (JTAG) is provided. This enables parallel use of tools for debugging and ETAS
tools for measurement and calibration.
