15.12.14 DT4 – Timer/Counter4 Dead Time Value
7766F–AVR–11/10
The dead time value register is an 8-bit read/write register.
The dead time delay of all Timer/Counter4 channels are adjusted by the dead time value regis-
ter, DT4. The register consists of two fields, DT4H3..0 and DT4L3..0, one for each
complementary output. Therefore a different dead time delay can be adjusted for the rising edge
of OC4x and the rising edge of OC4x.
• Bits 7:4- DT4H3:DT4H0: Dead Time Value for OC4x Output
The dead time value for the OC1x output. The dead time delay is set as a number of the pres-
caled timer/counter clocks. The minimum dead time is zero and the maximum dead time is the
prescaled time/counter clock period multiplied by 15.
• Bits 3:0- DT4L3:DT4L0: Dead Time Value for OC4x Output
The dead time value for the OC4x output. The dead time delay is set as a number of the pres-
caled timer/counter clocks. The minimum dead time is zero and the maximum dead time is the
prescaled time/counter clock period multiplied by 15.
