NOTES (WRITE CYCLE)
1. A write occurs during the overlap of a low CS and a low WE. A write begins at the latest transition among CS going Low and WE
going low : A write end at the earliest transition among CS going high and WE going high, tWP is measured from the begining of write
to the end of write.
2. t CW is measured from the CS going low to end of write.
3. t AS is measured from the address valid to the beginning of write.
4. t WR is measured from the end of write to the address change. tWR applied in case a write ends as CS or WE going high.
