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.

When using the internal clock source which is generated
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.
