BQ27531-G1: 400KHz I2C Communication delay required at boot up

Part Number: BQ27531-G1

Hi,

I'd just like to confirm if this statement from the reference manual is applicable when a battery is first attached to our system and the host MCU boot up and take the first voltage reading from the gauge:

"For read-write standard commands, a minimum of 2 seconds is required to get the
result updated."

I noticed that adding a delay of 2 seconds will make the first voltage reading successful. Removing the 2 seconds delay at bootup will result to 0V voltage reading for the first read attempt.

After reading the reference manual, I realized that even though the MCU is just reading the voltage, the first time the battery is attached could be considered a "read-write" scenario like when writing the gauge.

Could anyone confirm this? We'd like to know if the 2-second settling time is really the characteristic of the device. I

Thanks.
