2. 3 Part Names and Functions of 78K0-OCD Board
The 78K0-OCD board is used for debugging a 78K0 microcontroller (not used for flash programming). Figure
2-3 illustrates the external view of the 78K0-OCD board. The name of each part is printed on the 78K0-OCD
board. For each function, refer to
(1)
to
(4)
, below.
Figure 2-3. Part Names of 78K0-OCD Board
(1) CLK1
For clock supply to the target device, a 14-pin DIP socket is implemented as CLK1. A 14-pin type oscillator (5
V) or a parts board that can configure an oscillation circuit can be mounted on the 14-pin DIP socket. A parts
board such as the 160-90-314 (manufactured by PRECI-DIP) can be used with this socket to configure
oscillation circuit.
(2) CN1
This is a connector used to connect MINICUBE2 with the target interface connector of MINICUBE2. To
prevent the 78K0-OCD board from being inserted by mistake, a dummy pin is mounted in the place of pin 11 in
CN1.
(3) CN2
This is a connector used to connect MINICUBE2 with the target system, via a 10-pin target cable.
A 10-core 2.54 mm pitch general-purpose connector (TSM-105-01-L-DV) is employed.
(4) CN3
This is a connector used to connect MINICUBE2 with the target system, via a 16-pin target cable.
A 16-core 2.54 mm pitch general-purpose connector (TSM-108-01-L-DV) is employed.
