LTC6811 multicell monitor GUI

This red indication says there's a mismatch between what's written and what's read back from the CFG register of the device. You were writing 0xF8 into the CFG register of the device but what you read back is 0xD8 which is not the same as what's written.
The CFGR0 bytes consist of GPIOx bitfields which generally turn on/off the Internal Pull Down based on what's being written into it. But while reading back the same register, it checks what's the logic level on the pin and accordingly returns the result. 
I guess there's a GPIO Pullup resistor missing on the GPIO3 Pin on the demo board. Please confirm if your components in the board match the demo board schematics.

Hi SideshS,
Thank you for your support. I understood the behavior clearly.
