Return from subroutine.
The Program Counter is loaded with the return address (22 bit wide) read from the stack, and the Stack Pointer is incremented by 3.
The same as RET, but in addition sets the general interrupt flag (flag I in the Status Register).
Returns are the slowest instructions in the pAVR implementation of the AVR instruction set. They take 9 clocks.
First 2 clocks are spent while waiting the previous instructions to write the Unified Memory. Next 5 clocks, the Program Counter is read from the Unified Memory. In a future version, this part might take only 4 clocks. Finally, another 2 clocks are spent while bringing the target instruction into the instruction register.
