BQ27Z561-R1: I2C time out mechanism

Part Number: BQ27Z561-R1
Other Parts Discussed in Thread: BQ28Z610-R1

Shirish,

"10.2.2 I2C Time Out: The I2C engine releases SDA and SCL if the I2C bus is held low for about two seconds."

Let me further confirm above claim in our datasheet. At what circumstance, time out will be triggered? When 561 find SCL keeps low for 2s? And SCL is pulled low by 561? Then it release SCL?

Adding more CLK to send to SCL does solve the hang up problem in below thread. Customer still wonder why 561 doesn't time out and release SDA automatically.

Thanks a lot
