Function explanation : [Timer mode] [IGBT mode] [PMD mode]

Simulation : [Clock period (Timer mode)] [PPG output (IGBT mode)] [3-phase motor control (PMD mode)]

The source clock frequency of the 16-bit multi-purpose timer and the timer setting value are shown.

Setting method

  • Setting of system clock 
    The frequency of ΦT0 is determined in the system clock setting part.
  • Clock selection of the timer 
    Select clock output from prescaler in the timer.
  • Timer setting value 
    Input a numerical value to the preferred setting value, and select the unit. Clicking the calculation button will show you a timer setting value in the selected timer clock cycle.
