At Section 5.1.9.2.3 the I3C v1.1 Specification states: “I3C mandates a single-retry model for Direct GET CCC Commands.” Based on this statement, adopters have a general notion that the Master is required to retry once for the Directed GET CCCs if the Slave NACKs for the first time. This may not be applicable for other “read” Directed CCCs (such as RSTACT, MLANE, vendor read, etc.) that are not defined for dedicated Read CCCs (i.e., CCCs that have names of the form GETxxx).
