ADuCM33x: What specification of "Power-down" in kernel-flow?

Hi all.

We are evaluating the ADuCM330.
I have a question in kernel-operation.

What specification of "Power-down" in "ADuCM330/ADuCM331 Hardware Reference Manual UG-716 Rev. B | Page 27 of 126 Figure 4. ADuCM330/ADuCM331 Kernel Flowchart "
Could you please teach us the power-down control registers (POWCON, POWMOD, CLKCON,... and other)?

When I measured it, the current decreased after about 50 minutes from the LIN-download standby state,
and the IDD current at that time was about 5 mA.
Is this a reasonable value?

Best Regards
