Hi,
I have a question about the DB submodule of PWM.
The dead band operation mode is set to active / high complement.
When I checked the waveform with an oscilloscope, both the rising and falling edge delays were 10ns longer than the setting.
Is this a specification?
The settings related to the DB submodule are as follows.
- Epwm1Regs.DBCTL.bit.OUT_MODE = 0x3;
- Epwm1Regs.DBCTL.bit.POLSEL = 0x2;
- Epwm1Regs.DBCTL.bit.IN_MODE = 0x0;
- Epwm1Regs.DBCTL.bit.OUTSWAP = 0x0;
- Epwm1Regs.DBCTL.bit.DEDB_MODE = 0x0;
- Epwm1Regs.DBCTL.bit.HALFCYCLE = 0x0;
Thanks,
Koki
