Other Parts Discussed in Thread: BQ20Z655-R1

Hello!

For my new project I'm using BQ20z655-R1 with LCD. My question is about the LCD refresh frequency in the datasheet there are two diiferente infromations  for the same configuration. see the illustrations below.

So which is the correct information and why it doesn't appear on the table of data flash values?

can you explian me this point ?

    The correct default is 35Hz. The 20 to 100 Hz is the programmable range allowable using EVSW. The register can technically go to 255, but I believe the frequency will be capped to 100Hz if so. It looks like an error in the TRM that it was left out of the data flash table.
