PSRAM WRITE OPERATIONS
Notes:
1. Minimum value must be equal or greater than the sum of actual t
2. New write address is valid from either CE1r or WE that is brought to High.
3. Maximum value is applicable if CE1r is kept at Low and both WE and OE are kept at High.
4. The t
If actual value is shorter than specified minimum value, tOE becomes longer by the amount of subtracting actual
value from specified minimum value.
5. The t
6. t
In case OE is disabled after t
In other words, read operation is initiated if t
7. Applicable if CE1r stays Low after read operation.
