PRODUCTION DATA
The I2C engine releases SDA and SCL if the I2C bus is held low for two seconds. If the fuel gauge is holding the lines, releasing them frees them for the primary to drive the lines. If an external condition is holding either of the lines low, the I2C engine enters the low-power SLEEP mode.
