Hi all,
just looked through the ATTiny 861 datasheet with the "new" options to use a High-Frequency PLL clock with the 8 MHz calibrated oscillator to clock the processor and the periphials. So by using this combination, the processor can run at 16 MHz with the internal RC oscillator.
However, the datasheet also says that the maximum "speed" at 3.3V is 10 MHz. It doesn't say what this "10 MHz" is referring to. Is this the maximum speed of an externally attached clock signal (XTAL or external clock), is it the maximum CPU clock, the maximum IO clock, ...? Or, in other words, is it possible to use the High Frequency PLL clock for the CPU at 16 MHz with a 3.3V power supply?
