Notes:

Recommendation: Connect to VDDIO if not needed
Leave open if not needed
When using host interface in I²C mode: connect R1…R3 as indicated; Do not apply host connection to HCSB and HSDO; HSDO can be used for device address selection if needed
Host signal name depends on SPI/I²C configuration
Example configuration shows one external I²C bus on M3. Different configurations, e.g. using Ml and/or M2, are also possible
