* //we have fade_end interrupt and counter overflow interrupt. we just give an example of fade_end interrupt here.
* ledc_isr_register(18, ledc_isr_handler, NULL); //hook the isr handler for LEDC interrupt
* //the first parameter is INUM, you can pick one form interrupt level 1/2 which is not used by the system.
* //NOTE1:user should arrange the INUMs that used, better not to use a same INUM for different interrupt source.
* //NOTE2:do not pick the INUM that already occupied by the system.
* //NOTE3:refer to soc.h to check which INUMs that can be used.
* ----------------EXAMPLE OF INTERRUPT HANDLER ---------------
* #include "esp_attr.h"
* void IRAM_ATTR ledc_isr_handler(void* arg) //we should add 'IRAM_ATTR' attribution when we declare the isr function
* {
* uint32_t intr_st = LEDC.int_st.val; //read LEDC interrupt status.
*
* //you will find which channels have triggered fade_end interrupt here,
* //then, you can post some event to RTOS queue to process the event.
* //later we will add a queue in the driver code.
*
* LEDC.int_clr.val = intr_st; //clear LEDC interrupt status.
* }
