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 Controller is required to  retry once for the Directed GET CCCs if the Target NACKs the first try. 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).
