DWM3001C Low power mode

Hi, This is DWM3001C user.

I am using CLI(command line interface).

I realized when I put 5V on this, it works every transmission cycle,
but when I put only 3V, it still works but with less frequency. (4 errors, 1 successfully work)

I can understand, but it looks like the chip still working while they are not transmitting the data.
Which is very inefficient, just wasting the battery.

How to use DWM3001C efficiently with 3V? Is there sleep mode function by any chance?

Modification : I checked it is not about voltage, it is about protocol.

When I use V_USB, USB_N, USB_P, GND on Nordic MCU (nRF52833),
I could check the status become ok.

I guess through the USB, it makes wakeup event.

Anyway, my question is same.
