The PWE value is compared against the value written to this location to enable PW1 access. At power-on, the
PWE value is set to all 1s. Thus, writing these bytes to all 1s grants PW1 access on power-on without writing
the password entry. All reads of this register are 00h.

The PWE value is compared against the value written to this location to enable PW2 access. At power-on, the
PWE value is set to all 1s. Thus writing these bytes to all 1s grants PW2 access on power-on without writing
the password entry. All reads of this register are 00h.
