CE# may be asserted any time before or after WE# is asserted. If CE# is asserted after WE#, all timing relative to WE# asserted should be
referenced to the time CE# was asserted.
CE# may be negated any time before or after WE# is negated. If CE# is negated before WE#, all timing relative to WE# negated will be
referenced to the time CE# was negated.
