Bit 9 CC1OF: Capture/Compare 1 overcapture flag
Bit 8 B2IF: Break 2 interrupt flag
Bit 7 BIF: Break interrupt flag
Bit 6 TIF: Trigger interrupt flag
Bit 5 COMIF: COM interrupt flag
Bit 4 CC4IF: Capture/Compare 4 interrupt flag
Bit 3 CC3IF: Capture/Compare 3 interrupt flag
Bit 2 CC2IF: Capture/Compare 2 interrupt flag
Bit 1 CC1IF: Capture/Compare 1 interrupt 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 '0'.
0: No overcapture has been detected.
1: The counter value has been captured in TIMx_CCR1 register while CC1IF flag was
already set
This flag is set by hardware as soon as the break 2 input goes active. It can be cleared by
software if the break 2 input is not active.
0: No break event occurred.
1: An active level has been detected on the break 2 input. An interrupt is generated if BIE=1
in the TIMx_DIER register.
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.
0: No break event occurred.
1: An active level has been detected on the break input. An interrupt is generated if BIE=1 in
the TIMx_DIER register.
This flag is set by hardware on the TRG trigger event (active edge detected on TRGI input
when the slave mode controller is enabled in all modes but gated mode. It is set when the
counter starts or stops when gated mode is selected. It is cleared by software.
0: No trigger event occurred.
1: Trigger interrupt pending.
This flag is set by hardware on COM event (when Capture/compare Control bits - CCxE,
CCxNE, OCxM - have been updated). It is cleared by software.
0: No COM event occurred.
1: COM interrupt pending.

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).
0: No compare match / No input capture occurred
1: A compare match or an input capture occurred.
If channel CC1 is configured as output: this flag is set when he 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).
