Demonstrations for how TIMH output PWM waveform.

1. TIMH0 output PWM with interrupt. You can chose one of four type interrupt : TIMH_IT_TRIGA/TIMH_IT_TRIGB/TIMH_IT_TRIGC/TIMH_IT_UPDATE.
   PWM_H --> PC5
   PWM_L --> PC8
   
   1.1 PA0 will toggled in TIMH0 interrupt.

2. TIMH1 and TIMH2 output PWM without interrupt.

   TIMH1_PWM_H --> PC6
   TIMH1_PWM_L --> PC9
   
   TIMH2_PWM_H --> PC7
   TIMH2_PWM_L --> PC10
