The instruction call Rn,sub is a two word instruction.Assuming that PC is incremented during the fetch cycle of the first word of the instruction,its resister transfer operation is
Someone please help me to calculate minimum clock cycles needed during the execution cycle of the instruction.I am student of computer science and not very good in microprocessor ,please explain how to count minimum clock cycles?
Should it not be 5 in 8085.
- For loading PC to ALU register
- Cycle to increment PC (PC+1)
- Transferring it to Rn from accumulator.
- 2 cycles for memory read operation.
Please let me know where i am wrong ? Please.
