(6) Turning on the emulation adapter and base board and release from reset
Output 5 V from the power-supply unit that is connected to the CN3 power-supply connector of the
emulation adapter. When the IE850A is connected to CN3, output 5 V by turning on the emulator as
described in step (5) above. Then, turn the switch (SW1; POWER SW) of the base board on and set
SW2 (RESET SW) for the high level.
Accordingly, if an emulator is not connected, the debug chip will start executing a program.
When the emulator is connected, the debug chip will be kept in the reset state before execution of a
program is started by the debugger after the debugger has been launched, although this depends on
the specifications of the emulator.
CAUTION
Applied voltage:
Make sure that the voltage applied to CN3 is within the specified range (4.5 V to 5.5 V).
An applied voltage out of the range may cause the emulation adapter to emit smoke or
catch fire or otherwise be damaged.
(7) Launching the debugger (only if you are using an emulator)
Launch the debugger to start debugging. The first time this is done, an option byte must be set
according to the target device to be emulated.
