Return Address
After seven CALLs or six CALLs and an
interrupt, the stack looks like the figure
on the left. A series of RETURN instructions
will repeatedly place the return addresses
into the Program Counter and pop the stack.
STKPTR = 0x06
STKPTR = 0x00
This figure shows the stack configuration
after the first CALL or a single interrupt.
If a RETURN instruction is executed, the
return address will be placed in the
Program Counter and the Stack Pointer
decremented to the empty state (0x1F).
