2. These pins are used as address bus when selecting separate bus.
3. Bits PM15 and PM14 in the PM1 register determine which pin is used to output the ALE signal.
4. The PM02 bit in the PM0 register selects either combination, “RD, WRL, WRH” or “RD, BHE, WR”.
5. P5_6 outputs undefined value when bits PM15 and PM14 are set to 00b (no ALE). In this case, it cannot be
6. Bits PM11 and PM10 in the PM1 register determine whether these pins are used as chip-select outputs or
