Timer Output Example When TRnCE = 1 Is Set (Initial)
(PWM mode with Dead Time)
(5)
Dead time control in PWM mode with dead time
In the PWM mode with dead time, compare registers (TRnCCR1 to TRnCCR3) are used as the
duty setting registers, and another compare register (TRnCCR0) is used as the cycle setting
register. Through the use of these four registers, a variable duty 6-phase PWM waveform is
output. To realize dead time control, three 10-bit down counters that operate in synchronization
with the counter’s count clock, and dead time setting registers (TRnDTC0, TRnDTC1) are
provided. The TRnDTC0 register is used to set the dead time from when the inverted phase
becomes inactive to when the normal phase becomes active, and the TRnDTC1 register is used
to set the dead time from when the normal phase becomes inactive to when the inverted phase
becomes active.
The following figure shows an output example when TRnDTC0 = x, TRnDTC1 = y.
