Note 1: CE# may be asserted any time before or after WE# is asserted. If CE# is asserted after WE#, all timing relative to
WE# asserted will be referenced instead to the time CE# was asserted.
Note 2: 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 instead to the time CE# was negated.
