3v power-up problem with 16LF628 |

I have issue with a 16LF628 PIC that will not power up using a 3.1 v suppply. It works fine if I use a 5v supply but when I switch to a 3.1v supply, it just does not power-up. The fuses I set are:
#fuses INTRC_IO, NOLVP, NOWDT, MCLR, BROWNOUT, PUT
where the MCLR pin had a 10K to Vdd and a .1uF cap to gnd. I also tried it without the cap and using the NOMCLR fuse. Neither one worked with the 3.1v supply. If anyone has some pointers about how I should debug this I would sure appreciate some pointers.
Thanks,

So is there no way to use brown out with a lower voltage? |
