It's "break", not "brake" (also in some way I agree it does too ;)).
And "any more" is "anymore".

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?
