PICsters, I was reading about the TMRO on the PIC and I was wondering about the clock it u ses to divide using the prescaler. If I select the internal clock, does it use t he input frequency (4MHz OSC) or the 1MHz clock that the PIC instructions run at ? Also, if I select an external clock of say 32KHz, will it use that frequency i nputed into the prescaler or is their a divide by 4 their as well? Thanks in adv ance ........................ !
