Advanced-control timer (TIM1)
Bit 10 BK2CMP1P: BRK2 COMP1 input polarity
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
Bit 9 BK2INP: BRK2 BKIN2 input polarity
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
Bits 8:3 Reserved, must be kept at reset value.
Bit 2 BK2CMP2E: BRK2 COMP2 enable
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
Bit 1 BK2CMP1E: BRK2 COMP1 enable
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
Bit 0 BK2INE: BRK2 BKIN input enable
Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits
Note: Refer to
714/1306
This bit selects the COMP1 input sensitivity. It must be programmed together with the BK2P
polarity bit.
0: COMP1 input polarity is not inverted (active low if BK2P=0, active high if BK2P=1)
1: COMP1 input polarity is inverted (active high if BK2P=0, active low if BK2P=1)
in TIMx_BDTR register).
This bit selects the BKIN2 alternate function input sensitivity. It must be programmed
together with the BK2P polarity bit.
0: BKIN2 input polarity is not inverted (active low if BK2P=0, active high if BK2P=1)
1: BKIN2 input polarity is inverted (active high if BK2P=0, active low if BK2P=1)
in TIMx_BDTR register).
This bit enables the COMP2 for the timer's BRK2 input. COMP2 output is 'ORed' with the
other BRK2 sources.
0: COMP2 input disabled
1: COMP2 input enabled
in TIMx_BDTR register).
This bit enables the COMP1 for the timer's BRK2 input. COMP1 output is 'ORed' with the
other BRK2 sources.
0: COMP1 input disabled
1: COMP1 input enabled
in TIMx_BDTR register).
This bit enables the BKIN2 alternate function input for the timer's BRK2 input. BKIN2 input is
'ORed' with the other BRK2 sources.
0: BKIN2 input disabled
1: BKIN2 input enabled
in TIMx_BDTR register).
