NOTES:
1. If RP# is asserted while a block erase, full chip erase, (multi) word/byte write or block lock-bit configuration
operation is not executing, the reset will complete within 100ns.
2. A reset time, t PHQV , is required from the latter of STS going High Z or RP# going high until outputs are valid.
3. When the device power-up, holding RP# low minimum 100ns is required after V CC has been in predefined range
and also has been in stable there.
