Hello,
I am testing the BQ79616-Q1 EVM, and there is a question about GPIO measurements. If the GPIO pin is disabled, why the measurement is -5V?
Thanks and hope for your answer.

Hello,
This is normal behavior. This is because the register values default to 0xFF when GPIO voltages are turned off. Negative because registers for GPIO read in 2s compliment.
