Bits 31:18 Reserved, must be kept at reset value.
Bit 17 CC6IF: Compare 6 interrupt flag
Refer to CC1IF description (Note: Channel 6 can only be configured as output)
Bit 16 CC5IF: Compare 5 interrupt flag
Refer to CC1IF description (Note: Channel 5 can only be configured as output)
Bits 15:14 Reserved, must be kept at reset value.
Bit 13 SBIF: System Break interrupt flag
This flag is set by hardware as soon as the system break input goes active. It can be
cleared by software if the system break input is not active.
This flag must be reset to re-start PWM operation.
0: No break event occurred.
1: An active level has been detected on the system break input. An interrupt is generated if
BIE=1 in the TIMx_DIER register.
Bit 12 CC4OF: Capture/Compare 4 overcapture flag
Refer to CC1OF description
Bit 11 CC3OF: Capture/Compare 3 overcapture flag
Refer to CC1OF description
Bit 10 CC2OF: Capture/Compare 2 overcapture flag
Refer to CC1OF description
