Tool/software:

Hi team,

I'm BCCing the customer as this may be related to quality issue.

If user sets both EN_PDR and EN_STC set, which priority is higher?

If the control would be a kind of hybrid, do you have any behavior example for doubling above two settings?

Best regards,

Shoji

Hi,

Thank you for your questions. EN_PDR and EN_STC is different function and impacting to different part of driving.

PDR will impact to A, STC will impact to B.

Note: If PDR of t_DON_DOFF_xx is set to small, feedback loop may not work correctly. Normally better to start with more than 0Ah(Default). If some strange behavior was observed, do not use less than 0Ah.

regards

Shinya
