Notes: 1. These are the names of the MCU pins at the time the E1 or E20 is connected (i.e. during
debugging).
2. Input to or output from the user system.
3. Securely connect pin 5 and the GND bus lead of the connector to GND on the user system.
These are used as electrical GND and for the E1 or E20 to monitor connection to the user
system.
4. The EMLE pin can operate even if it is not connected to the E1 or E20 emulator. When the pin is
not connected to the E1 or E20 emulator, a special circuit for the pin must be configured on the
user system.
If the MCU does not have an EMLE pin, it is not necessary to connect it to the emulator
connector. In this case, only FINE Interface Connection is available.
5. The MD0 and MD1 pin can operate even if it is not connected to the E1 or E20 emulator. When
the pin is not connected to the E1 or E20 emulator, a special circuit for the pin must be
configured on the user system.
You cannot debug a program in boot mode.
