Update interrupt flag This bit is set by hardware on an update event. It is cleared by software. At overflow regarding the repetition counter value (update if repetition counter = 0) and if the UDIS=0 in the TIMx_CR1 register. When CNT is reinitialized by software using the UG bit in TIMx_EGR register, if URS=0 and UDIS=0 in the TIMx_CR1 register.
Type Definitions
Field BIF reader - Break interrupt flag This flag is set by hardware as soon as the break input goes active. It can be cleared by software if the break input is not active.
Field BIF writer - Break interrupt flag This flag is set by hardware as soon as the break input goes active. It can be cleared by software if the break input is not active.
Field CC1IF reader - Capture/Compare 1 interrupt flag This flag is set by hardware. It is cleared by software (input capture or output compare mode) or by reading the TIMx_CCR1 register (input capture mode only). If channel CC1 is configured as output: this flag is set when the content of the counter TIMx_CNT matches the content of the TIMx_CCR1 register. When the content of TIMx_CCR1 is greater than the content of TIMx_ARR, the CC1IF bit goes high on the counter overflow (in up-counting and up/down-counting modes) or underflow (in down-counting mode). There are 3 possible options for flag setting in center-aligned mode, refer to the CMS bits in the TIMx_CR1 register for the full description. If channel CC1 is configured as input: this bit is set when counter value has been captured in TIMx_CCR1 register (an edge has been detected on IC1, as per the edge sensitivity defined with the CC1P and CC1NP bits setting, in TIMx_CCER).
Field CC1IF writer - Capture/Compare 1 interrupt flag This flag is set by hardware. It is cleared by software (input capture or output compare mode) or by reading the TIMx_CCR1 register (input capture mode only). If channel CC1 is configured as output: this flag is set when the content of the counter TIMx_CNT matches the content of the TIMx_CCR1 register.

Field CC1OF reader - Capture/Compare 1 overcapture flag This flag is set by hardware only when the corresponding channel is configured in input capture mode. It is cleared by software by writing it to ’0â.
Field CC1OF writer - Capture/Compare 1 overcapture flag This flag is set by hardware only when the corresponding channel is configured in input capture mode. It is cleared by software by writing it to ’0â.
Field COMIF reader - COM interrupt flag This flag is set by hardware on a COM event (once the capture/compare control bits âCCxE, CCxNE, OCxMâ have been updated). It is cleared by software.
Field COMIF writer - COM interrupt flag This flag is set by hardware on a COM event (once the capture/compare control bits âCCxE, CCxNE, OCxMâ have been updated). It is cleared by software.
Field UIF reader - Update interrupt flag This bit is set by hardware on an update event. It is cleared by software. At overflow regarding the repetition counter value (update if repetition counter = 0) and if the UDIS=0 in the TIMx_CR1 register. When CNT is reinitialized by software using the UG bit in TIMx_EGR register, if URS=0 and UDIS=0 in the TIMx_CR1 register.
