The I3C v1.1.1 specification has updated the format of the GETCAP Format 1 (Direct) CCC figure in Section 5.1.9.3.19 to make it clearer that I3C Devices that comply with I3C version 1.1 or greater are required to return at least 2 bytes for this CCC. In earlier I3C specification versions, this figure showed four possible options, one of which allowed a single data byte (i.e., GETCAP1 alone). While this was valid for an I3C Device that complied with version 1.0 and supported the GETHDRCAP CCC (the precursor to the GETCAPS CCC), it was not helpful for new I3C Device implementers. The updated figure in v1.1.1 now shows the supported options for I3C v1.1 and higher Devices.
