NOTES:
 If multiple slaves are connected to the I2C signals in addition to this device, only 1 pull-
up resistor on each of SDA and SCL should exist. Also, care must be taken to not
violate the I2C specification for capacitive loading.
 When pin VDD/VDDIO is not powered and set to 0V, INTN, SDA and SCL will be held
to VDD plus the forward voltage of the internal static protection diodes, typically about
0.6V.
 When pin VDD/VDDIO is disconnected from power or ground (e.g. Hi-Z), the device
may become inadvertently powered up through the ESD diodes present on other
powered signals.
