37.2.7.2.13 Set Bus Context (SETBUSCON)

The Controller uses the Broadcast SETBUSCON CCC to specify a particular context that is being used on the bus, which is stored in the I3CxBUSCXT register. The context is usually a higher-level protocol specification published by a standards-developing organization that relies upon MIPI I3C® for the communication (such as JEDEC or MCTP), but it may also indicate which version of the MIPI I3C Specification is being used. Upon receiving this CCC, the user can activate any special functionality in the software needed to support the selected higher-level protocol on the bus. The frame format for Broadcast Write SETBUSCON CCC is shown in Figure 37-41.

Important: This Target device only supports single context value. Layered protocol contexts are not supported.
