That's actually from an 18F datasheet, but I would expect the same
behavior in a 16F.  I've observed program memory reads failing on a
16F during an EEPROM write; I'm assuming that this is because the
EEDATA/EEADR registers are simply non-functional, as noted in the 18F
datasheet, while an EEPROM write is in progress.
