STACK OPERATION EXAMPLE 

 
The two kinds of Stack-Save operations to reference the stack pointer (STKP) and write the program counter contents 
(PC) into the stack buffer are CALL instruction and interrupt service. Under each condition, the STKP is decreased and 
points to the next available stack location. The stack buffer stores the program counter about the op-code address. The 
Stack-Save operation is as following table.

There is a Stack-Restore operation corresponding each push operation to restore the program counter (PC). The RETI 
instruction is for interrupt service routine. The RET instruction is for CALL instruction. When a Stack-Restore operation 
executes the STKP increases and points to the next free stack location. The stack buffer restores the last program 
counter (PC) to the program counter registers. The Stack-Restore operation is as following table.
