The GPIOR0, 1 & 2 do not all respond to the instructions specified. Only 
GPIOr0 does. I use the LDS and STS with all 3.
If you look at the RET and RETI instructions, the stack operations are the 
same, according to the manual. However, the RET does return to the 
instruction following the CALL whereas the RETI returns to the instruction 
at point of interrupt. In the case of the RETI, after much debate and RTFM 
bull, you have to use a polled type of interrupt.
