Notes 1. This connection is designed assuming that the RESET signal is output from the N-ch open-drain buffer
(output resistance: 100
Ω
or less). For details, refer to 4.1.3 Connection of reset pin .
2. For debugging, mount no clock circuit. For flash programming, mount a clock circuit.
3. During debugging, the clock mounted on the 78K0-OCD board can be supplied. If no clock is mounted, a
clock of 4, 8, or 16 MHz can be supplied.
4. The circuit enclosed by a dashed line is designed for flash self programming, which controls the FLMD0 pin
via ports. Use the port for inputting or outputting the high level. When flash self programming is not
performed, a pull-down resistance for the FLMD0 pin can be within 1 to 10 k
Ω
.
5. OCD1A may be a different name, such as P31, depending on the device used. For details, refer to the
user's manual for the target device.
