The issue of temporary waveform discrepancy occurring during the initial PWM output in S32K146

[00ill]

Currently, the phase shifted as much as 90 degrees, and channels 1 and 3 are High Side, and channels 2 and 4 are Low Side, and the ratio of High Side is raised by 1 every 1ms.(From the top, number 1)

However, you can see a waveform with a duty ratio of about 50% in 3, 4 Channel.

How Can I Fix it?

Hi @00ill,

Do you use SDK/RTD drivers?

If so, which version?

If not, do you follow the Initialization Procedure, RM rev.14, Section 47.8?

Can you share the code?

Regards,

Daniel
