During Bus initialization, the I3C Controller assigns a 7-bit Dynamic Address to each Device on the I3C Bus. For this to happen, each Target device must have a 48-bit Provisioned ID (that is, each Target is provisioned with its ID). The Provisioned ID has multiple fields, including MIPI Manufacturer ID and a vendor-defined part number. The I3C Target may also have a Static Address; if the Controller knows the Static Address, it allows for faster assignment of the Dynamic Address.
