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.
Write cycle time is limited by the sum of tw(WE) and trec(WE).
Applies to the cycle which immediately follows entering Power Down mode and to special Paged RAM cycle which start a download
operation: after writing to the Paged RAM selected Register following cycle (generally the first polling cycle) actually starts the download
process. This spec applies to the period following that cycle, i.e. the time between the first and second polling cycles.
