Stack Area

The stack provides the area where the return address is

saved before a jump is performed during the processing

routine at the execution of a subroutine call instruction or

the acceptance of an interrupt.

When returning from the processing routine, executing the

subroutine return instruction [RET] restores the contents of

the program counter from the stack; executing the interrupt

return instruction [RETI] restores the contents of the pro-

gram counter and flags.

The save/restore locations in the stack are determined by

the stack pointed (SP). The SP is automatically decreased

after the saving, and increased before the restoring. This

means the value of the SP indicates the stack location

number for the next save.
