Setup Pins
Setup pins are strapped high or low to configure options according to system design. For low, strap to
ground. Many pins have internal pullups on their input buffers. These pins can be left unconnected to keep
them in high state.
CPU Type Selection
(nRWM/SCM[1]: Pin)
[nRWM=H, nDSINV=H]
[nRWM=L, nDSINV=L or H]
Peripheral mode: This pin selects the CPU type; in this case, the definition of nWR/DIR (pin) and
nRD/nDS (pin) are selected (refer to Figure 3 - Motorola CPU Mode (68hxx).
Standalone mode: This pin is the clock –master-ID-specification input SCM[1].
