Hi
According to the ATMega128 documentation, bit 0 of RAMPZ selects the high or
low page access of Z pointer, with the other bits of RAMPZ unused. However
it appears that setting RAMPZ to 3 causes elpm return garbage. This behaviour
seems to break pgm_read_byte_far(). Anybody else noticed this ?.
Cheers
