1.5.2
Recommended Circuit (14-Pin Type)
Figure 1.5 shows a recommended circuit between the H-UDI port connector and the MPU.
Notes: 1. Do not connect anything to the N.C. pin of the H-UDI port connector.
2.
The processing of the /ASEMD0 pin differs depending on whether the emulator is
used or not. As the emulator does not control this pin, it must be controlled by a
switch on the board.

used or not. As the emulator does not control this pin, it must be controlled by a
switch on the board.
(1)
When the emulator is used: /ASEMD0 = low (ASE mode)
(2)
When the emulator is not used: /ASEMD0 = high (normal mode)
3.
The reset signal in the user system is input to the /RESETP pin of the MPU. Connect
this signal to the H-UDI port connector as the output from the user system.

4.
When a joined resistance is used for pull-up, it may be affected by a noise. Separate
TCK from other resistances.
TCK from other resistances.
5.
When the emulator is in use, pin 11 of the H-UDI connector must be pulled up by a
resistance of several kilo-ohms.
resistance of several kilo-ohms.
6.
The pattern between the H-UDI connector and the MPU must be as short as possible.
Do not connect the signal lines to other components on the board.
Do not connect the signal lines to other components on the board.
7.
The resistance values shown in figure 1.5 are recommended.
