MOTES:
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 1OOns.
3. A reset time, tpHov, 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 1OOns is required after Vcc has been in predefined range
and also has been in stable there.
