How to off BOR on DSPIC33EV

Hi guys,
 
In my board, i use 3.3V voltage supply for chip DSPIC33EV.
How can I disable Brown-out reset on chip?
It is my mistake when read datasheet, forgot about BOR voltage.
 
Thanks,
Bang Duong

Open the datasheet.
Go to the electric specification chapter.
Look at the first table, which has the Vdd range.
What do you see?
 
Or, if you want, the very first line on the very first page: operating conditions.

Oh, is all that hassle about your software not running without ebugger that your board has got a 3.3 V supply?
Nice. Help yourself and modify your board to run from a 5 V supply.
 
Advice: don't try to ignore the data from the datasheet: if it tells you "4.5 .. 5.5 V"7 you can't run the controller from 3.3 V.
