Yeah one more layer of confusion, sorry :/

By "asserting WP" I mean driving the line to a state where
writing to the EEPROM is enabled, i.e. the default state is
that the EEPROM is write protected and when you "assert"
WP it becomes writable.

If you feel the inverse semantics are more intuitive (such that
WP comes up asserted and thus write protected), be my
guest :D

As long as it is unambiguously documented in the bindings
and with comments in the code I'm game for whatever the
at24 people feel is most appropriate. (You will set the standard
for everyone else.)

Yours.
