Introduction to the Timing Diagram T-State: T State is defined as one subdivision of the operation performed in one clock period. Call Instructions - The call instruction transfers the program sequence to the memory address given in the operand. Before transferring, the address of the next instruction after CALL is pushed onto the stack. Call instructions are 2 types: Unconditional Call Instructions and Conditional Call Instructions. 2. Write timing diagram for CALL and RET instructions of 8085 and explain, with RTL activities, why the opcode fetch cycle take extra T states in CALL instruction? --- 15 M ; Question: 2. Write timing diagram for CALL and RET instructions of 8085 and explain, with RTL activities, why the opcode fetch cycle take extra T states in CALL Timing Diagram of 8085: Timing Diagram of 8085 Collected by C.Gokul, AP/EEE, VCET-Erode References: 1.8085 microprocessor by Sajid Akram , researcher/lecturer at c.abdul hakeem college of engineering and technology 2.Timingdiagram by puja00 (slideshare.net) 3.Microprocessor 8086 by Gopikrishna Madanan , Assistant Professor of Physics at Collegiate Education, Kerala, India Timing diagram 8085 microprocessor 1.

Memory Read Machine Cycle of 8085: ü The memory read machine cycle is executed by the processor to read a data byte from memory. ü The processor takes 3T states to execute this cycle. The instructions which have more than one byte word size will use the machine cycle after the opcode fetch machine cycle. Cycle 3. Explain the sequence of events during the execution of the CALL instruction by 8085 processor with the help of neat timing diagram. 1 See answer Advertisement Advertisement balochbohair22 is waiting for your help.

(The 8085 have a maximum clock frequency of 5 MHz and therefore a minimum state length of 200 nanoseconds.) and
