217 / 467 page ![]() DocID14587 Rev 14 217/467 RM0016 16-bit advanced control timer (TIM1) 261 17.7.31 Deadtime register (TIM1_DTR) Address offset: 0x1E Reset value: 0x00 7 654 3210 DTG7:0] rw rw rw rw rw rw rw rw Bits 7:0 DTG[7:0]: Deadtime generator set-up This bitfield defines the duration of the deadtime inserted between the complementary outputs. DT corresponds to this duration. tCK_PSC is the TIM1 clock pulse. DTG[7:5] = 0xx => DT= DTG[7:0] x tdtg with tdtg = tCK_PSC (f1) DTG[7:5] = 10x => DT= (64 + DTG[5:0]) x tdtg with tdtg= 2 x tCK_PSC (f2) DTG[7:5] = 110 => DT = (32 + DTG[4:0]) x tdtg with tdtg= 8 x tCK_PSC (f3) DTG[7:5] = 111 => DT = (32 + DTG[4:0]) x tdtg with tdtg = 16 x tCK_PSC (f4) Example If tCK_PSC= 125 ns (8 MHz), deadtime possible values are: DTG[7:0] = 0 x 0 to 0 x 7F from 0 to 15875 ns in 125 ns steps (refer to f1) DTG[7:0] = 0 x 80 to 0 x BF from 16 µs to 31750 ns in 250 ns steps (refer to f2) DTG[7:0] = 0 x C0 to 0 x DF from 32 µs to 63 µs in 1µs steps (refer to f3) DTG[7:0] = 0 x E0 to 0 x FF from 64 µs to 126 µs in 2 µs steps (refer to f4) Note: This bitfield can not be modified while LOCK level 1, 2, or 3 have been programmed (LOCK bits in the TIM1_BKR register). |
