HOW to check the signal BATLOW via i2c

Hi there,
How i can read the BATLOW pin in R32.2.0? I viewed : 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 I want to make sure Does this REG 0x13 is correspond to pin C7?

I think should read the REG 6

Thank you for you reply! Could you share this file to me or where can I get this file?
