15.11
15.11.1 Push Operation
When a subroutine is called, the return address is
pushed onto the subroutine stack. Specifically, each
address in the stack is moved to the next lower level in
order to make room for the new address to be stored.
Stack 1 receives the contents of the program counter.
Stack 8 is overwritten with what was in Stack 7. The con-
tents of stack 8 are lost.
Subroutine Operation
15.11.2 Pop Operation
When a return instruction is executed the subroutine
stack is popped. Specifically, the contents of Stack 1 are
copied into the program counter and the contents of each
stack level are moved to the next higher level. For exam-
ple, Stack 1 receives the contents of Stack 2, etc., until
Stack 7 is overwritten with the contents of Stack 8. Stack
8 is left unchanged, so the contents of Stack 8 are dupli-
cated in Stack 7.
