How to perform asynchronous PWM output/

Question

I am performing PWM output using the PWM output/Diagnostic function of RH850 U2A. 
 When PWM output is performed using three channels, the three channels are synchronized. 
 I would like to output PWM on each channel with a fixed time delay. 
 I am thinking of outputting asynchronously. 
 However, I cannot find a register related to phase setting. 
 How can I generate a phase difference to enable PWM output?

Hi pistons7 (00u13o7h9fazHRVNd358), The RH850/U2A-EVA Group User&rsquo;s Manual: Hardware (renesas.com) 
 provides detailed information on the Dead Time Module within the Generic Timer Module (GTM) , as outlined in Section 38.18 . This module offers the precise functionality you are seeking. 
 Additionally, I recommend reviewing the following application note: RH850/U2B UVW phase PWM output using GTM (renesas.cn) . While the document specifically targets the U2B device, the GTM peripheral implementation is very similar and offers relevant insights into configuring UVW phase PWM generation using GTM. 
 I hope this answer helps

Thanks for the diagram. It looks like you have a 3 phase motor control application - correct? If that is the case, the U2A comes with a dedicated timer for these applications (see section 35). With this module, you can simply configure a dedicated phase shift for every channel of the timer. The output/diagnostics function is not designed to be used for any phase delays/ phase shifts. Its purpose lies in providing integrated fault monitoring and protective gating of the PWM outputs&mdash;allowing the hardware to instantly blank or shut down all channels in response to comparator trips, overcurrent events, or other safety‑critical fault conditions. I hope this helps.
