Bits 15:11 Reserved, must be kept at reset value.
Bit 10 CC2OF: Capture/Compare 2 overcapture flag
Refer to CC1OF description
Bit 9 CC1OF: 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 ‘0’.
0: No overcapture has been detected
1: The counter value has been captured in TIM15_CCR1 register while CC1IF flag was
already set
Bit 8 Reserved, must be kept at reset value.
Bit 7 BIF: 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.
0: No break event occurred
1: An active level has been detected on the break input
Bit 6 TIF: Trigger interrupt flag
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, both edges in case
gated mode is selected). 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
Bit 5 COMIF: COM interrupt flag
This flag is set by hardware on a COM event (once the capture/compare control bits –CCxE,
CCxNE, OCxM– have been updated). It is cleared by software.
0: No COM event occurred
1: COM interrupt pending
Bits 4:3 Reserved, must be kept at reset value.
