NOTES:
1. If RP# is asserted while a block erase or word/byte write operation is not executing, the reset will complete within 100ns.
2. A reset time, t , is required from the later of RY/BY# 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 has been in predefined range and also
CC
has been in stable there.
