Hi there,
How i can read the BATLOW pin in R32.2.0? I viewed :https://forums.developer.nvidia.com/t/bat-low-pin-status-checking/47001.then I checked the value of i2c4 0x3c REG 0X13 that not change whatever the battery power is low or high.But the value of the pin C7 is correct.so I want to make sure Does this REG 0x13 is correspond to pin C7?

I think should read the REG 6
