Section 4 Example of Emulator Connection
Notes: 1. E10T_0 to E10T_2 pins are used by the emulator. Pull up and connect the emulator
and MCU pins.

2. The NMI# signal is used for forced break control by the emulator. Connect the
emulator and MCU pins directly. In debugging without forced break control, change
the mode with the High-performance Embedded Workshop. Then, when the user
logic is connected with the open-collector output buffer, the NMI# pin can be used in
the user system (however, at power-on, the NMI# pin is used by the emulator).
