Functions

IntStatus PWM_GetIntStatus (LPC_PWM_TypeDef *PWMx, uint32_t IntFlag)
 Check whether specified interrupt flag in PWM is set or not.
void PWM_ClearIntPending (LPC_PWM_TypeDef *PWMx, uint32_t IntFlag)
 Clear specified PWM Interrupt pending.
void PWM_ConfigStructInit (uint8_t PWMTimerCounterMode, void *PWM_InitStruct)
 Fills each PWM_InitStruct member with its default value:

  • If PWMCounterMode = PWM_MODE_TIMER: + PrescaleOption = PWM_TIMER_PRESCALE_USVAL + PrescaleValue = 1
  • If PWMCounterMode = PWM_MODE_COUNTER: + CountInputSelect = PWM_COUNTER_PCAP1_0 + CounterOption = PWM_COUNTER_RISING.
