The following table shows the jumper selections available for this board.
When a SPC8108 is installed, set JPI and JP2 to position 1-2. When a SPC8106 is installed, set
JPI and JP2 to position 2-3. See “SDU8106B0E Rev. 1.0 Schematic Diagrams” on page 16.
If enabled, a vertical retrace will generate an interrupt on the SPC8106F0C IRQ pin. To connect
IRQ to ISA bus IRQ9, set jumper JP3 to position 1-2; otherwise set the jumper to position 2-3.
To support 16-bit panels using an external latch, set JP4 to position 1-2 and remove the 16-pin
DIP shunt at U9. (Configuration input MD7 must also be set to the open position). When the
SPC8106 is in non-CRT mode, the SPC8106 can directly drive a 16-bit panel by setting JP4 to
position 2-3 and installing the DIP shunt at U9. (Configuration input MD7 must also be set to the
closed position).
