Note: Refer to Section 28.3.2: TIM1/TIM8/TIM20 pins and internal signals for product specific
implementation.
Bit 5 BKCMP5E: tim_brk_cmp5 enable
This bit enables the tim_brk_cmp5 for the timer’s tim_brk input. tim_brk_cmp5 output is
‘ORed’ with the other tim_brk sources.
0: tim_brk_cmp5 input disabled
1: tim_brk_cmp5 input enabled
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
Bit 4 BKCMP4E: tim_brk_cmp4 enable
This bit enables the tim_brk_cmp4 for the timer’s tim_brk input. tim_brk_cmp4 output is
‘ORed’ with the other tim_brk sources.
0: tim_brk_cmp4 input disabled
1: tim_brk_cmp4 input enabled
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
Bit 3 BKCMP3E: tim_brk_cmp3 enable
This bit enables the tim_brk_cmp3 for the timer’s tim_brk input. tim_brk_cmp3 output is
‘ORed’ with the other tim_brk sources.
0: tim_brk_cmp3 input disabled
1: tim_brk_cmp3 input enabled
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
Bit 2 BKCMP2E: tim_brk_cmp2 enable
This bit enables the tim_brk_cmp2 for the timer’s tim_brk input. tim_brk_cmp2 output is
‘ORed’ with the other tim_brk sources.
0: tim_brk_cmp2 input disabled
1: tim_brk_cmp2 input enabled
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
Bit 1 BKCMP1E: tim_brk_cmp1 enable
This bit enables the tim_brk_cmp1 for the timer’s tim_brk input. tim_brk_cmp1 output is
‘ORed’ with the other tim_brk sources.
0: tim_brk_cmp1 input disabled
1: tim_brk_cmp1 input enabled
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
Bit 0 BKINE: TIMx_BKIN input enable
This bit enables the TIMx_BKIN alternate function input for the timer’s tim_brk input.
TIMx_BKIN input is ‘ORed’ with the other tim_brk sources.
0: TIMx_BKIN input disabled
1: TIMx_BKIN input enabled
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
