Board Switches and Jumpers +1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC8360E PB 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. Heed + well the names and labels and do not get confused. + + "Off" == 1 + "On" == 0 + + SW18 is switch 18 as silk-screened onto the board. + SW4[8] is the bit labled 8 on Switch 4. + SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2. + SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3. + SW3[1:8]= 0000_0001 refers to bits labeled 1 through 6 is set as "On" + and bits labeled 8 is set as "Off". + +1.1 For the MPC8360E PB PROTO Board + + First, make sure the board default setting is consistent with the document shipped with your board.
