Hi Loic,
Sorry for the delay - I needed to investigate a little more. You are correct that the TRM table does need to be updated. I will get this updated in the next revision of the document.
However, after looking more at your image of the Register screen, I am not sure why you say the CHG FET is enabled. I circled the CHG bit below which is green indicating the CHG FET is off. The xCHG bit indicates that charging is enabled which is correct since the device is pre-charging. It does not refer to the FET state.
Best regards,
Matt
