Wow, that was a quick reply! Thank you.
Post a link to the web page for the board.
The board was designed by someone long gone, it's not
not a publicly available part.
I'll try the high ... |

I have a board using a PIC18F2620 that has pads for an SMD
crystal. Previously, this board was used without the
crystal and with the internal oscillator. There are no
capacitors with the crystal; I ... |

Great lead, and prompt response, thanks.
I looked up your references
and then learned that the board has a .01uF
cape on the VCAP/VDDCORE pin, not the 1-10
uF specified. I didn't design it, bu ... |

on a dsPIC 33J128GP802? after a few (varies) seconds of
normal operation. I can't find any info on BROWNOUT for
this chip, and BROWNOUT_EN ... |

Hi-
I am a dsPIC newbie, and have been trying to nail down the cause of a
restart loop in PCI33F code that I inherited. The ASM code that apparently
causes the reset is:
