BQ34Z100-G1 current returned message format

Hi, I'd like to know what is the format of the response message for the 0x0A command (AverageCurrent), regarding to the sign. When discharging, the current is negative, and when charging, current is positive, right? The sign bit is bit 13 (14th bit), or it is the last bit of the response (bit 15)? I'm trying to display the current value when charging and discharging, and I just can't do it. There's something wrong with my C logic.

Thanks,
