from OPENice-i500, join connector 2-3 and 4-5 pin. If

 

 

 

user wants to use the external clock source like a crystal,

 

 

 

user should change the jumper setting from 1-2 to 5-6

 

 

 

and connect Y1 to an external clock source.

NOTE: S3F80JB Target board consists of 74HC11N, regulator and other components. In case of 74HC11N, typical operating voltage is 5V. So 80jb target board includes a regulator for 3.3V generation. As you know, S3F80JB typical operating voltage is 3.3V. Although open-i500 supports 3.3 V for target board ‘s power source, we recommend that you connect jumper of open-i500 power source to 5V. Check the interface board’s jumper status between emulator and target board.

nRESET LED

This LED is OFF when the Reset switch is ON.

IDLE LED

This is LED is ON when the evaluation chip (S3E80JB) is in idle mode.

STOP LED

This LED is ON when the evalution chip (S3E80JB) is in stop mode.
