It also provides the bipolar bus drive capability and optimizes the system performance. 8288 8288 8288 Interfacing 8288 with 8086  Timing Diagrams for 8086 All the operations in 8086 are carried out with a particular sequence in a synchronized manner, so it is necessary to understand the Timing Diagrams. Clock Waveform: It represents the crystal controlled signal sent to 8086 from an external clock generator 8284. Clock, T- State and Machine cycle Timing diagram for Read machine cycle Timing diagram for Write machine cycle Maximum Mode-Read machine cycle Maximum Mode-Write machine cycle
