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 of CE# 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 instead to the time of CE# negated.
WE# may be asserted before or after the rising edge of AVD#. The beginning of the WE# asserted pulse width spec is measured from the
later of the falling edge of WE# or the rising edge of AVD#.
