Контроллер ШИМ: список регистров

  PWM_ENTIRE_CYCLE

Number of the entire cycles in the PWM clock
0: 1 cycle
1: 2 cycles
***
N: N+1 cycles
If the register need to be modified dynamically, the PCLK should be faster
than the PWM CLK.

Number of the active cycles in the PWM clock
0: 0 cycle
1: 1 cycle
***
N: N cycles
