Refer to Section 28.3.2: TIM1/TIM8/TIM20 pins and internal signals for product specific
information.
Note: These bits can not be modified as long as LOCK level 1 has been programmed (LOCK
bits in TIMx_BDTR register).
Bits 15:14 Reserved, must be kept at reset value.
Bit 13 BK2CMP4P: tim_brk2_cmp4 input polarity
This bit selects the tim_brk2_cmp4 input sensitivity. It must be programmed together with the
BK2P polarity bit.
0: tim_brk2_cmp4 input is not inverted (active low if BK2P=0, active high if BK2P=1)
1: tim_brk2_cmp4 input is inverted (active high if BK2P=0, active low if BK2P=1)
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
Bit 12 BK2CMP3P: tim_brk2_cmp3 input polarity
This bit selects the tim_brk2_cmp3 input sensitivity. It must be programmed together with the
BK2P polarity bit.
0: tim_brk2_cmp3 input is not inverted (active low if BK2P=0, active high if BK2P=1)
1: tim_brk2_cmp3 input is inverted (active high if BK2P=0, active low if BK2P=1)
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
Bit 11 BK2CMP2P: tim_brk2_cmp2 input polarity
This bit selects the tim_brk2_cmp2 input sensitivity. It must be programmed together with the
BK2P polarity bit.
0: tim_brk2_cmp2 input is not inverted (active low if BK2P=0, active high if BK2P=1)
1: tim_brk2_cmp2 input is inverted (active high if BK2P=0, active low if BK2P=1)
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
in TIMx_BDTR register).
