General Description

The following pin function descriptions are for 8088 systems in either minimum or maximum mode The ‘‘local bus’’ in these descriptions is the direct multiplexed bus interface connection to the 8088 (without regard to additional bus buffers) Symbol Pin No Type Name and Function AD7–AD0 9–16 I O ADDRESS DATA BUS These lines constitute the time multiplexed memory IO address (T1) and data (T2 T3 Tw T4) bus These lines are active HIGH and float to 3-state OFF during interrupt acknowledge and local bus ‘‘hold acknowledge’’ A15–A8 2–8 39 O ADDRESS BUS These lines provide address bits 8 through 15 for the entire bus cycle (T1 – T4) These lines do not have to be latched by ALE to remain valid A15 – A8 are active HIGH and float to 3-state OFF during interrupt acknowledge and local bus ‘‘hold acknowledge’’ A19 S6 A18 S5 35–38 O ADDRESS STATUS During T1 these are the four most significant A17 S4 A16 S3 address lines for memory operations During I O oper
