I am at the stage of uploading the Arduino bootloader via SPI comms to the ATMEGA328 so I can then upload the ... E.g. for an ATtiny @ 128 kHz: the datasheet states that both the high and low // SPI clock pulse must be > 2 ...

Posts about atmega328p written by feilipu. ... However, all AVR ATmega devices have a watchdog timer which is driven by an independent 128kHz internal oscillator. Arduino doesn't configure the watchdog timer, and conveniently the ...

The 128KHz clock is for very low power applications where running the chip very slowly helps conserve power. Having an internal oscillator means we don't need to wire up a crystal and we can use the clock pins for our own nefarious purposes .
