Calculate t states of an instruction?

For calculating the T states of the any instruction ,you should know how many machine cycles does the instruction contains and the number of T states in each of the machine cycles

for example,

In a 8085 microprocessor set ,the instr. JMP contains three machine cycles

• opcode fetch which is of 4T or 6T states
• memory read which is of 3T states
• another memory read which is again of 3T states

Therefore , the instr. JMP has a total of 10T states
