/ 8)
(i.e. 000: 735 ps, 001= 1.471 ns,...)
This bitfield is read-only as soon as any of the lock bit is enabled (DTFLKs, DTFSLKx, DTRLKx,
DTRSLKx).
Bit 9 SDTRx: Sign deadtime rising value
This register determines whether the deadtime is positive or negative (overlapping signals).
0: Positive deadtime on rising edge
1: Negative deadtime on rising edge
Bits 8:0 DTRx[8:0]: Deadtime rising value
This register holds the value of the deadtime following a rising edge of reference PWM signal.
