It will also drive an output RESET HIGH pulse at the emulator RST-pin. If the crystal oscillator is selected with whe low speed option (32kHz), the low speed RC oscillator must not be used. In this case the WDT will also use the low speed crystal oscillator. 8.1. Using the WDT To ...
If the duty cycle of the PWM signal varies with time and you filter the PWM signal, the output of the fil-ter is an analog signal (Figure 1). If you build a PWM DAC in this manner, its resolution is equivalent to the resolution of the PWM signal you use to create the DAC.Mike ...

If you build a PWM DAC in this manner, its resolution is equivalent to the resolution of the PWM signal you use to create the DAC. The PWM output signal requires a frequency that is equivalent to the update rate of the DAC, because each change in PWM duty cycle is the equivalent of ...
