It's a problem with the simulator. In short, CPU registers are accessed through their SRAM addresses and X+ addressing, but R27 (XH) is not initialized so contains semi-random values. For an ATtiny2313, this doesn't matter as it only implements 8-bit SRAM addressing, but the simulator thinks SRAM outside the address space is being accessed, and refuses to load the values. -- cheers, Joerg .-.-. --... ...-- -.. .
