4.1 Recommended Circuit (36-Pin Type)
Figure 4.1 shows a recommended circuit between the H-UDI port connector (36 pins) and the
MCU.
Notes: 1. Do not connect anything to the N.C. pin of the H-UDI port connector.

2. When a joined resistance is used for pull-up, it may be affected by a noise. Separate
3. The reset signal in the user system is input to the /RESETP pin (pin 220) of the MCU.
4. When the emulator is used, the AUDCK pin must be an end resistance (pulled up or
5. The processing of the /ASEMD0 pin differs depending on whether the emulator is used
6. The pattern between the H-UDI port connector and the MCU must be as short as
7. The resistance values shown in figure 4.1 are recommended.

When the emulator is used: /ASEMD0 = low (ASE mode)
When the emulator is not used: /ASEMD0 = high (normal mode)
