2.3 Examples of recommended connections between the 14-pin connector and
MCU
Different tools are used with the E2 emulator according to whether the purpose is debugging or flash
programming. Table 2-6 shows the relationships between the operating modes and connection interfaces.

MULTI in the remainder of this document.
This section describes examples of recommended connections between the 14-pin connector for the E2
emulator and the target device. Since there are various examples of recommended connections according to
the purpose of the E2 emulator, select the appropriate circuit with reference to Table 2-7. Be sure to take the
specifications of the target device as well as measures to prevent noise into consideration when designing
your circuit.
