UJA1132HW3V3 HVIO Read status issue

I'm developing one product using UJA1132HW3V3 and S32K148. I'm trying to configure the HVIOs on UJA1132HW3V3 as wake up inputs and trying to read the status of the wake up input.

However, I got full zeros when using SBC_Transfer function in SDK to access the "Bank 0 wake-up status register" and "Bank 1 wake-up status register".

Meanwhile, I also could not read out the HVIOn(1-4, and 5-8) control registers using the SBC_Transfer function.

Can you support me on this topic? Thanks!


My SDK version is: S32SDK_S32K1xx_RTM_3.0.0
