DT1A – Timer/Counter1 Dead Time A
The dead time value register A is an 8-bit read/write register.
The dead time delay of is adjusted by the dead time value register, DT1A. The register consists of two fields,
DT1AH[3:0] and DT1AL[3:0], one for each complementary output. Therefore a different dead time delay can be
adjusted for the rising edge of OC1A and the rising edge of OC1A.
Bits 7:4 – DT1AH[3:0]: Dead Time Value for OC1A Output
The dead time value for the OC1A output. The dead time delay is set as a number of the prescaled 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 – DT1AL[3:0]: Dead Time Value for OC1A Output
The dead time value for the OC1A output. The dead time delay is set as a number of the prescaled timer/counter
clocks. The minimum dead time is zero and the maximum dead time is the prescaled time/counter clock period
multiplied by 15.
14.1.3
DT1B – Timer/Counter1 Dead Time B
The dead time value register Bis an 8-bit read/write register.
The dead time delay of is adjusted by the dead time value register, DT1B. The register consists of two fields,
DT1BH[3:0] and DT1BL[3:0], one for each complementary output. Therefore a different dead time delay can be
adjusted for the rising edge of OC1A and the rising edge of OC1A.
Bits 7:4 – DT1BH[3:0]: Dead Time Value for OC1B Output
The dead time value for the OC1B output. The dead time delay is set as a number of the prescaled 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 – DT1BL[3:0]: Dead Time Value for OC1B Output
The dead time value for the OC1B output. The dead time delay is set as a number of the prescaled timer/counter
clocks. The minimum dead time is zero and the maximum dead time is the prescaled time/counter clock period
multiplied by 15.
