Brown Out detection Levels in LPC11U67

Dears,

I want to use brown out detection in my microprocessor. In the user manual only levels are indicated, but I can't find which voltage ratio (compared to Vdd) corresponds to every level.
For example, with a voltage supply of 3.3V and a BOD level 3, which is the voltage level?

Best Regards,

Mattia

Is it possible to know where you found it?
