Timer/Counter1 Dead Time A - DT1A
Timer/Counter1 Dead Time B - DT1B
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, DT1AH3..0 and DT1AL3..0, one for each complementary output. Therefore a differ-
ent dead time delay can be adjusted for the rising edge of OC1A and the rising edge of OC1A.
• Bits 7..4- DT1AH3..DT1AH0: 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- DT1AL3..DT1AL0: 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, DT1BH3..0 and DT1BL3..0, one for each complementary output. Therefore a differ-
ent dead time delay can be adjusted for the rising edge of OC1A and the rising edge of OC1A.
• Bits 7..4- DT1BH3..DT1BH0: 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- DT1BL3..DT1BL0: 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.
