22. 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 in non-multiplexed modes.
23. Multiplexed inputs: any of the following inputs that are latched by the ALE (or AS):
A0/AD0–A15/AD15, CSI/A19 as ALE dependent A19, ALE dependent PC0–PC2.
24.CSOi = any of the chip-select output signals coming through Port B (CS0 – CS7) or through
Port C (CS8 – CS10).
25.CSOi product terms can include any of the PAD input signals shown in Figure 3, except for reset
and CSI.
