Board Switches and Jumpers +1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC8360EMDS 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.
