There is an example of a LHLD 5000H diagram on this website: atelier-drachenhaus.de/timing-diagram-8085. This will provide an idea of how to draw the diagram.
There are 74 instructions in the 8085 microprocessor.
timing
stores next instructions
The timing diagram for the LDA (Load Accumulator Direct) instruction in the 8085 microprocessor involves several key phases. Initially, the opcode is fetched from memory, which takes 4 clock cycles. Next, the address of the data to be loaded into the accumulator is specified in the next two cycles, followed by another two cycles to read the data from the specified memory location into the accumulator. The entire process typically takes 7 machine cycles, including the necessary memory access time.
because the operand is available in the instruction itself
It provides timing signals.
We can implement "Divided by '2' " operation by using RRC.
8085 is a microprocessor designed by Intel
The OUT instruction on the 8085 uses 10 T cycles, 3 for opcode fetch, 1 for opcode decode, 3 for port address fetch, and 3 for port data store. Any wait states encountered are above and beyond that.
In the 8085 microprocessor, the opcode fetch machine cycle is not sufficient on its own for executing the MOV MA instruction. While the opcode fetch cycle is responsible for retrieving the instruction from memory, additional machine cycles are required to perform the data transfer or execution of the instruction. Specifically, the MOV MA instruction involves both an opcode fetch cycle and a memory access cycle to complete the operation. Therefore, multiple machine cycles are necessary for executing this instruction effectively.
