Verify that a P-Flash block is erased.
Verify that a given number of words starting at the address provided are erased.
Read a dedicated 64 byte field in the nonvolatile information register in P-Flash block that was
previously programmed using the Program Once command.
Program a phrase in a P-Flash block.
