Hi all
anyone one have any experience using the ULPWU (ultra low power wake up) module on the PIC12F635 ?
it seems to have started life in the PIC16F684
looking for any tips or code snips using PBP

i need to also use the PLVD (programmable low voltage detect) module but at 20+ uA i don't have the power budget to leave it on all the time for low battery warning indication

so my thought is to use the ULPWU (if i can figure it out) and wake up once in a while and enable the PLVD to sniff the battery

at first read it looks like the ULPWU will interrupt and wake up the unit roughly every 30ms using a 1000pf cap
this way too often for me, guess i could keep a counter or something

but using PBP it is not clear to me how to proceed
make the pin an output, set HI briefly, turn it back to an input and go to sleep?
something like that ?

TIA
