first Op Code of a subroutine is to be fetched. At the end of the subroutine,
a RETurn instruction can be used to return to the original program flow by
popping the top of the stack back to PC. If condition
Program Counter is incremented as usual, and the program continues with
the next sequential instruction. The stack push is accomplished by first
decrementing the current contents of the Stack Pointer (SP), loading the
high-order byte of the PC contents to the memory address now pointed to
by SP; then decrementing SP again, and loading the low order byte of the
PC contents to the top of the stack.
Because this is a 3-byte instruction, the Program Counter was incremented
by three before the push is executed.
