byte is defined as an 8-bit variable:
unsigned char byte;
when call printf function, the compiler loads it to D0 (8-bit) register and then transfers to D2 (16-bit) register, then pushes the 16 bits value to stack. But in the printf, it is retrieved as an 8-bit value from stack. Is it a compiler bug?
