They say that VRC for LDO3 is enabled if the bit is 0, disabled when the bit is 1. And that the default value is enabled.
Yes you are correct (and well spotted) that the datasheet is wrong. It took us some time to figure out why it wasn't working :)
I thought I updated the wiki, but I must have done it incorrectly. I will fix it immediatly.
Please also leave a note there saying the datasheet is wrong.
Thanks ChenYu
