Open Drain – External Pull-up is required
Note 2: Note that pull-ups on I2C lines (SDAs/SCLs) are not included on the module and need to be provided externally. See
Section “I2C Pull-Up Resistance” for more information on the pull-up resistor sizes.
Note 3: Host_int signal should be connected to GPIO of Host MCU which can be used as an interrupt source. SA0 signal can
be used to resolve unlikely I2C address alias problem on the Host I2C bus.
Note 4: In most applications SA0 can be connected to ground (see Section “Host I2C Interface (Host Bus)” for more details).
