Missing information in LPC55S1x datasheet

The datasheet for the LPC55S1x does not include information abot termination of DCDC related pins in case the DCDC block is not used.

I think it should be in the "6.1.2 Using the Internal DC-DC converter" but no text is included in this section, only a figure of how to use the DCDC block.

Hello @alexis_marquet 

As you mention, there is not much information about the related pins when this block is not used, but this is because we do not recommend avoiding this feature. In any case, you could refer to this community post for more information about bypassing the DC-DC converter on a similar LPC: https://community.nxp.com/t5/LPC-Microcontrollers/Properly-bypassing-LPC5500-s-internal-DCDC-convert...

 

Best regards,

Edwin.
