|  | description: | | 
|  | This property provides a byte which should used to enable non-permanent | 
|  | readout protection (RDP1). Actually, any byte except 0xAA and 0xCC | 
|  | (which are used by RDP0 and RDP2 respectively) can be used to enable | 
|  | RDP1 but in multi-image environment, some other image could check if | 
|  | RDP1 is enabled by comparing it to some hardcoded value. The byte has to | 
|  | be different than 0xAA and 0xCC. |
