9.7.5.3.1 Command and Response Structure

The command port of I3CC accepts the following four types of command structures to initiate a transfer on the I3C bus:

Address Assignment
Immediate Data Transfer
Regular Data Transfer
Combo Transfer

Each command comprises two 32-bit words. The I3CC issues the command on the I3CC line only after receiving two 32-bit words. If the I3CC receives a partial command, then the I3CC waits until it receives the complete command to initiate the transfer.
