pic16LF819 not working with 3.3V

[jjohannson]

I found in the sheets that if VDD goes below 4V a reset on brown out can occur and keep the chip from firing up.
I have a line of code that reads

@ DEVICE XT_OSC, MCLR_OFF

I think this assembly statelment sets or resets configuration bits. I do not know the syntax for turning off or on other configuration bits. Does anyone know how to reset BOR or where this information is.

I think what Ron was trying to say is: The oscillator gets more power when HS is set instead of XT. I read that somewhere.

[jjohannson]

I tried the HS setting and it still does not work. I think it has something to do with the Reset on Brown Out and I don't know how to deactivate the BOR

[jjohannson]

'@DEVICE BOD_OFF' is what needed to be included. Does anyone know where I can find the information for the different configuration bit codes. i.e MCLR_OFF, XT_OSC, BOD_OFF etc.

[Archangel]

Try for mpasm @ __CONFIG & _BODEN_OFF
for PM @ DEVICE PIC16LF819, BOD_OFF

I am not sure if this pic has BOD, still looking at the data sheet
edit: Yep as Paul correctly stated, info found in m16f81x.inc file

It is BOD_OFF you need (as you noted)
- see datasheet section 12.1
- see 16F819.inc file in your PBP folder
- see m16F819.inc in your INC folder in your PBP folder
