Hi Knowledgeable Helpers. I'm using an ATTiny13. If I load immediate data (LDI) to a register ( r16) and it already contains a value, does loading new data add to the existing value in the register or does the instruction LDI clear the register and load only the immediate data? Any help would be greatly appreciated.
