4.2.7
Emulation of the SVR
The emulation adapter mounts the power-supply IC which is used to generate VDD for the debug chip.
When VDD that has been generated in the SVR circuit on the user system is to be supplied to the
debug chip, short-circuit pins 2-3 of jumper block JP5. Since SVRPGATE and SVRNGATE signals are
supplied through the exchange adapter and the characteristics of these signals will differ from those of
the signals when the actual device is connected, reviewing the SVR parameters may be required or
operation of the SVR circuit may not be correct.
4.2.8
Emulation of the Ethernet TSN (ETN)
The Ethernet TSN (ETN) may not operate normally due to the delay or load produced by the wiring
pattern on the user system.

Note on Debugging
4.3.1
Enabling C&R Authentication
If the ICU-M core of the debug chip on the emulation adapter is enabled and C&R authentication of the
debug chip is enabled for a program that fails C&R authentication, note that starting the debugger and
disabling C&R authentication will not be possible.
