Dead Time Control in 120-DC Mode
In 120-DC mode, the dead time is controlled on falling of each phase, and the
dead time is added.
The dead time set in TSnDTC1 is inserted on falling of the positive phase, and
the dead time set in TSnDTC0 is inserted on falling of the inverse phase.

Output Switch Example
Caution
The dead time control method may affect the timer output. The timer output
may not have the specified active level width due to the dead time control
under the following conditions:
• When noise is generated on the input pattern in the pattern switch method
• When a change in the input pattern occurs earlier than the PWM period in
the pattern switch method
• When TSnOPT1.TSnSPC2 to TSnSPC0 are changed and the output
pattern is forcibly changed in the trigger switch method
• When switch method is changed
• When the current direction control bit (TSnOPT0.TSnIDC) is changed
• When the software output control function is used
(11)
Output Switch in 120-DC Mode
In 120-DC mode, the output pattern can be controlled by writing values to
TSnOPT1.TSnSPC2 to TSnSPC0 when the trigger switch method
(TSnOPT0.TSnSTE = 1, and TSnPOT = 1) is used. The dead time is secured
by hardware at the switch timing.
Caution
When 111
B
or 000
B
is written to TSnSPC2 to TSnSPC0, the TSG2nO1 to
TSG2nO6 pins are driven low.
