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].
