The Stack Pointer decrements by two, the current contents of the Program Counter, which
is the address of the first instruction following the CALL instruction, are pushed onto the
top of the stack and the specified destination address is then loaded into the Program
Counter. The Program Counter now points to the first instruction of the procedure.
At the end of the procedure, a RET instruction returns to the original program flow. RET
pops the top of the stack and replaces the original value into the Program Counter.
Using Escaped Mode Addressing, address mode IR specifies a Working Register. If the
destination address is prefixed by
ple, if Working Register R12 (
