5 Connectors

In this chapter, the connectors of the SK-MB91594-208M04 are described.

With the OCD connector (on chip debugging) it is possible to flash the MCU and debug the

program via a single wire interface. However, this requires the additional MB2100-01-E

Embedded Emulator device (not provided with this starter-kit). The centre pin of the

connector X1 is connected to the MCU pin 134 (DEBUGIF). The following picture shows the

connections of X1.

There also is the possibility to access the DEBUGIF signal via Test Point TP3.

The following picture shows the power connector X2. A regulated DC power supply of 9V

that can support at least 500mA can be attached to power the board. The anode of the

power connector is the centre pin and the ground is connected to the shield. The board is

protected against an interchange of the pins.

J1, J2 and J3 are standard 2.54mm pitch headers. The following table explains these

headers.

J4 header offers an alternate way of video input apart from the Video Jack X12. It is

explained below.
