ADi = any address line.
CSOi = any of the chip-select output signals coming through Port B (CS0–CS7) or through Port C (CS8–CS10).
Direct PAD input = any of the following direct PAD input lines: CSI/A19 as transparent A19, RD/E, WR or R/W,
transparent PC0–PC2, ALE (or AS).
Control signals RD/E or WR or R/W.
