DT1A – Timer/Counter1 Dead Time A
DT1B – Timer/Counter1 Dead Time B
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 dif-
ferent 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 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 – 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 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.
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 dif-
ferent 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 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 – 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 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.
