10.10.10 PWM mode with dead time
(1)
Outline of PWM mode with dead time
In the PWM mode with dead time, 6-phase PWM is generated using the 16-bit counter’s saw tooth
wave operation and four 16-bit counters. The counter’s maximum value is set with the TRnCCR0
register. The duties of the U phase, V phase, and W phase voltage data signals are set with the
TRnCCR1 to TRnCCR3 registers. The dead time is set with the TRnDTC0 and TRnDTC1
registers, and the dead time for inverted phase
→
normal phase and the dead time for normal
phase
→
inverted phase can be independently set with the TRnDTC0 register and TRnDTC1
register, respectively. The counter’s operation consists in performing up count with 0000H as the
minimum value, and when the maximum value (cycle) indicated by the TRnCCR0 register is
matched, the counter is cleared (0000H), and the counter continues up-count operation.
The 10-bit dead time counters (TRnDTT1 to TRnDTT3) reload the setting value of the TRnDTC0
and TRnDTC1 registers upon a match between the counter and the TRnCCR1 to TRnCCR3
registers, and perform down count.
Upon a match between the 16-bit counter and the TRnCCR0 to TRnCCR3 registers, the
corresponding compare match interrupts (INTTRnCC1 to INTTRnCC3) are output.
