8-bit micro-controller build-in 12-bit ADC  
STACK REGISTERS  
The stack pointer (STKP) is a 4-bit register to store the address used to access the stack buffer, 12-bits data memory  
(STKnH and STKnL) set aside for temporary storage of stack addresses.  
The two stack operations are writing to the top of the stack (Stack-Save) and reading (Stack-Restore) from the top of  
stack. Stack-Save operation decrements the STKP and the Stack-Resotre operation increments one time. That makes  
the STKP always points to the top address of stack buffer and writes the last program counter value (PC) into the stack  
buffer.  
The program counter (PC) value is stored in the stack buffer before a CALL instruction executed or during interrupt  
service routine. Stack operation is a LIFO type (Last in and first out). The stack pointer (STKP) and stack buffer  
(STKnH and STKnL) are located in the system register area bank 0.  
STKP (stack pointer) initial value = 0xxx 1111
