Address Multiplex Selection
(nMUX/SCM[0]: Pin)
In peripheral mode, this pin specifies the system data bus from bit5 to 0 and whether or not the addresses
are multiplexed (Refer to Figure 5 - Non-Multiplex Bus). When the multiplexing bus option is selected, the
polarity of A2/ALE is specified based on A3/ALEPOL. In standalone mode, this pin is the clock-master-ID-
specification input SCM[0].
