i.MX6solo MAPSR register Should bit16 be set?

Hi NXP.
I have a question about the i.MX6 solo's MAPSR register.
Looking at the register details in 45.12.17, the reset value of bit16 is 0.
Therefore, I think it is appropriate to set bit 16 to 0 when writing to the MAPSR register.

However, as shown below, in the document, 1 is set when writing to the MAPSR register.

ex1) 45.8 LPDDR2 Refresh Rate Update and Timing Derating
1. Set MAPSR to 0x00010107
5. Write MAPSR to 0x00010106 to re-enable this feature

 

ex2) i.MX6DL Register Programming Aids

In the Excel file, 1 is written as a fixed value to bit 16 of the MAPSR register.

Should bit16 be set to 1 when writing to the MAPSR register?
I would like to know the recommended value to write to bit16.

Best regards.
