8.60 READ PASSWORD OPERATION (RDPWD, E7h)

The correct password value may be read only after it is programmed and before the Password Mode has been

selected by programming the Password Protection Mode bit to “0” in the ASP Register (ASP[2]). After the Password

Protection Mode is selected the RDPWD command is ignored.

The RDPWD command is shifted in. Then the 64-bit Password is shifted out, least significant byte first, most

significant bit of each byte first. Each bit is shifted out at the SCK frequency by the falling edge of the SCK signal.

It is possible to read the Password continuously by providing multiples of 64bits.
