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 /RES pin (SH7144F: pin 84,
4. When the emulator is used, the AUDCK pin must be an end resistance (pulled up or
