PF3001 unused LICELL pin

Hi

 

I'm confusing recommended external cap value for LICELL pin because there are vary as following.

https://www.nxp.com/docs/en/data-sheet/PF3001.pdf


p9 Coin cell supply input/output. Bypass with 0.1 μF capacitor. Connect to optional coin cell.

p40 Coin cell battery backup
      A 0.47 μF capacitor should be placed from LICELL to ground under all circumstances.

p41 Table 57. Coin cell charger external components
      LICELL bypass capacitor 100 nF

p79 Figure 26. Typical application schematic
      220nF

I guess the value in p9,p41 and p79 for the cap with coin cell and the value in p40 for the cap (with or) without coin cell.

 

Now I think there is no issue to eliminate coin cell like following.

Which one recommended 0.1uF or 0.47uF for the cap of LICELL pin without coin cell?

 

Can anyone help me?
