Address Multiplex Selection
(nMUX: Pin)
In Peripheral mode, this pin specifies the system data bus from bit 5 to 0 and whether the addresses are
multiplexed (Refer to Figure 5 - Non-multiplex Bus, Figure 6 - Multiplex (ALE falling-edge Type) and Figure
7 - Multiplex (ALE rising-edge Type). When the multiplexing bus option is selected, the polarity of A2/ALE
is specified based on A3/ALEPOL.
