NOTES:
1. These specifications are valid for all product versions (packages and speeds).
2. If RP » is asserted while a block erase, byte write, or lock-bit configuration operation is not executing,
the reset will complete within 100 ns.
3. A reset time tPHQV, is required from the latter of RY »/BY » or RP » going high until outputs are valid.
