| Oct 27, 2022 at 1:32 | comment | added | slebetman | @Newbie Are you asking how it starts with the internal oscillator? It is configured to do so. Or are you asking how it starts so that it can listen for code and configuration to be uploadable? The PIC's programming system is pure hardware based and does not use a clock at all. Instead the programmer (USB device, parallel port dongle etc.) will clock in the bit stream using one of the programming pins into the MCU the same way you'd use a memory device (RAM, ROM, SD Card etc). And just like a memory device (eg. SD Card) the PIC's programming system does not use any other clocks for its logic | |
