LMX2615-SP: Questions about Table 19 vs Table 54

Tool/software:

Hello,

Q1:
The LMX2615-SP datasheet table 19 says R75 bit 11 is 1b, but table 54 says it is 0b (Reserved bit). Which is true?

Q2:
The LMX2615-SP datasheet table 19 says R9 bit 11-0 are 0x604, but table 54 says they are 0x000.  Which is true?

Best regards,
