Difference between CALL and JUMP instructions

CALL instruction is used to call a subroutine. Subroutines are often used to perform tasks that need to be performed frequently. The JMP instruction is used to cause the PLC (Programmable Logic Control) to skip over rungs.

The differences Between CALL and JUMP instructions are:

SERIAL NO.	JUMP	CALL
1.	Program control is transferred to a memory location which is in the main program	Program Control is transferred to a memory location which is not a part of main program
2.	Immediate Addressing Mode	Immediate Addressing Mode + Register Indirect Addressing Mode
3.	Initialisation of SP(Stack Pointer) is not mandatory	Initialisation of SP(Stack Pointer) is mandatory
4.	Value of Program Counter(PC) is not transferred to stack	Value of Program Counter(PC) is transferred to stack
5.	After JUMP, there is no return instruction	After CALL, there is a return instruction
6.	Value of SP does not changes	Value of SP is decremented by 2
7.	10 T states are required to execute this instruction	18 T states are required to execute this instruction
8.	3 Machine cycles are required to execute this instruction	5 Machine cycles are required to execute this instruction
