Board Switches and Jumpers ++1.0 There are five Dual-In-Line Packages(DIP) Switches on MPC832XE SYS board ++ For some reason, the HW designers describe the switch settings ++ in terms of 0 and 1, and then map that to physical switches where ++ the label "On" refers to logic 0 and "Off" is logic 1. ++ ++ Switch bits are numbered 1 through, like, 4 6 8 or 10, but the ++ bits may contribute to signals that are numbered based at 0, ++ and some of those signals may be high-bit-number-0 too.
