Recommended Circuit for Connection
(14-pin type)
When a joined resistance is used for pull-up, it may be affected by a noise. Separate
TCK from other resistances.
The reset signal in the user side is input to the /RESET pin (pin 198) of the SH7750R.
Connect this pin to the H-UDI port connector as the output from the user system.
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.
The resistance values shown in figure 1.2 are recommended.
For the pin processing in cases where the emulator is not used, refer to the hardware
manual of the related device.
