Reset cause register for Allwinner H3/R16 SOC's

Hi All,

I am working on an Allwinner R16 and H3 based targets and I am implementing system update.

Is there any way(or a register) on Allwinner R16/H3 which can tell what is the cause of the reset(whether the reset is triggered by a watchdog or thermal or reset or a POR).

Thanks & Regards
