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 decremented  
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.

Table 3-1. STKP, STKnH and STKnL relative of Stack-Save Operation  
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  
occurs, the STKP is incremented 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.
