Hi chuluezhong,
I understand the issue you are having.
As I told above, if you used driver code is v1.0.0 RTM then you must used the corresponding PEx component(SDK_MPC574x_06). Then you generate configuration for MPC5744P it will not generate the fields: toggleTime, extMode, openDrain and triggerTimeIRQDMA.
If you are using S32DS version: 2017.R1 please update SDK MPC574xx RTM 1.0.0 to be able to use the driver and PEx component corresponding: link download SDK MPC574xx RTM REV UP5 - UP6
If you have installed SDK MPC574xx RTM REV UP5 - UP6 into S32 Design Studio for Power Architecture 2017.R1 then please switch workspace to an other workspace to S32DS update new software(PEx component).
Used driver code is v1.0.0 RTM and PEx component with BETA 1.9.0 - SDK_MPC574x_04 => error.

Used driver code is v1.0.0 RTM and PEx component with RTM 1.0.0 - SDK_MPC574x_06 => success.

If you have any issue please let me know.
Thank you.
