BKINE=B_0x0, BKINP=B_0x0, ETRSEL=B_0x0
TIM1 alternate function option register 1
| BKINE | BRK BKIN input enable This bit enables the BKIN alternate function input for the timerâs BRK input. BKIN input is 'ORedâ with the other BRK sources. Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits in TIMx_BDTR register). 0 (B_0x0): BKIN input disabled 1 (B_0x1): BKIN input enabled |
| BKINP | BRK BKIN input polarity This bit selects the BKIN alternate function input sensitivity. It must be programmed together with the BKP polarity bit. Note: This bit can not be modified as long as LOCK level 1 has been programmed (LOCK bits in TIMx_BDTR register). 0 (B_0x0): BKIN input polarity is not inverted (active low if BKP=0, active high if BKP=1) 1 (B_0x1): BKIN input polarity is inverted (active high if BKP=0, active low if BKP=1) |
| ETRSEL | ETR source selection These bits select the ETR input source. Others: Reserved Note: These bits can not be modified as long as LOCK level 1 has been programmed (LOCK bits in TIMx_BDTR register). 0 (B_0x0): ETR legacy mode 1 (B_0x1): COMP1 output 2 (B_0x2): COMP2 output 3 (B_0x3): ADC1 AWD1 4 (B_0x4): ADC1 AWD2 5 (B_0x5): ADC1 AWD3 |
