Bit 8 B2IF: Break 2 interrupt flag

Bit 4 CC4IF: Capture/compare 4 interrupt flag
Bit 3 CC3IF: Capture/compare 3 interrupt flag
1142/2083
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 tim_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.
