If eeprom data memory writes are asyncronous, why would reading eeprom data
memory during a write be prohibited? If it is prohibited, how would it
manifest itself? Return invalid data? Halt execution until the write
completed?  It seems as though if any of those behaviors were true, *that*
would certainly be documented. (One would hope!)
