COP8SAx7 MICROCONTROLLER
RETI
The Stack Pointer (SP) is first incremented. The contents of the data
memory location referenced by SP are then transferred to PCU (Upper
7 bits of PC), and SP is again incremented. Next, the contents of the data
memory location referenced by SP are transferred to PCL (Lower 8 bits
of PC). The return address has now been retrieved from the software
stack in data memory RAM. The program now jumps to the program
memory location accessed by PC. The Global Interrupt Enable flag (GIE)
is set to 1.
PCU <- [SP + 1]
PCL <- [SP + 2]
[SP + 2] : SET UP FOR NEXT STACK REFERENCE
