Wouldn't it be safer to default to 8-bit and have a switch to use 16-bit addressing? From what you said, "reading from an 8bit eeprom using 16bit addressing can actually *write* to the eeprom", but what would reading a 16-bit eeprom using 8-bit addressing do? If it isn't dangerous, I believe you should default to 8-bit addressing. BTW, isn't it possible to detect the addressing mode? -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
