Dead time control in high-accuracy T-PWM mode
In the high-accuracy T-PWM mode, the TRnCCR1 to TRnCCR3 registers are used for duty setting
and the TRnCCR0 register is used for cycle setting. By using these four registers, duty variable
type 6-phase PWM waveform can be output. To implement dead time control, there are three 10-
bit down-counters that synchronously operate with the count clock of the 16-bit counter, and two
dead time setting registers (TRnDTC0, TRnDTC1).
The TRnDTC0 register is used to set the dead time from when a negative phase changes to inac-
tive until a positive phase changes to active. The TRnDTC1 register is used to set the dead time
from when a positive phase changes to inactive until a negative phase changes to active.
The output waveform in case of TRnDTC0 = x, TRnDTC1 = y is shown below.
