Field BKBID reader - Break Bidirectional In the bidirectional mode (BKBID bit set to 1), the break input is configured both in input mode and in open drain output mode. Any active break event asserts a low logic level on the Break input to indicate an internal break event to external devices.

Field BKDSRM reader - Break Disarm This bit is cleared by hardware when no break source is active.

Note: Any write operation to this bit takes a delay of 1 APB clock cycle to become effective.

Field DTG reader - Dead-time generator setup This bit-field defines the duration of the dead-time inserted between the complementary outputs. DT correspond to this duration. DTG[7:5]=0xx => DT=DTG[7:0]x tDTG with tDTG=tDTS. DTG[7:5]=10x => DT=(64+DTG[5:0])xtDTG with tDTG=2xtDTS. DTG[7:5]=110 => DT=(32+DTG[4:0])xtDTG with tDTG=8xtDTS. DTG[7:5]=111 => DT=(32+DTG[4:0])xtDTG with tDTG=16xtDTS. Example if tDTS=125 ns (8 MHz), dead-time possible values are: 0 to 15875 ns by 125 ns steps, 16 μs to 31750 ns by 250 ns steps, 32 μs to 63 μs by 1 μs steps, 64 μs to 126 μs by 2 μs steps Note: This bit-field can not be modified as long as LOCK level 1, 2 or 3 has been programmed (LOCK bits in TIMx_BDTR register).
