80 CMA24BT cpuModule

BDM-610000087 Rev A

Jumper Settings and Locations

Many cpuModule options are configured by positioning jumpers. Jumpers are labeled on the board as

followed by a number.
Figure 7 shows the jumper locations that are used to configure the cpuModule. Table 52 lists the jumpers

and their settings.
