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