Valid Censorship Passwords

Is there any information on what a valid password is for use in censoring a device?  The Reference Manual for the MPC5674F states that a "valid password" should be programmed but I cannot find any mention of what "valid" entails. 


Certain flash passwords, generally ones with low values, do not appear to work correctly.  For instance a password of 0x1 will not allow the device to be accessed over JTAG.  Other passwords work just fine.  I can verify that both the control word and password are set correctly so I know it's not a problem with that.
