CAPDHOFF=B_0x0, CAPGRP=B_0x0
I3C controller-role capability register
CAPDHOFF | delayed controller-role hand-off This bit is written by software during bus initialization (i.e. I3C_CFGR.EN=0) and indicates if this target I3C may need additional time to process a controller-role hand-off requested by the current controller. This bit is used to return the CRCAP2 byte in response to the GETCAPS CCC format 2. 0 (B_0x0): this I3C does not needs additional time to process a controller-role hand-off 1 (B_0x1): this I3C needs additional time to process a controller-role hand-off |
CAPGRP | group management support (when acting as controller) This bit is written by software during bus initialization (i.e. I3C_CFGR.EN=0) and indicates if the I3C is able to support group management when it acts as a controller (after controller-role hand-off) via emitted DEFGRPA, RSTGRPA, and SETGRPA CCC. This bit is used to return the CRCAP1 byte in response to the GETCAPS CCC format 2. 0 (B_0x0): this I3C does not support group address capabilities 1 (B_0x1): this I3C supports group address capabilities (when becoming controller) |
