Refer to Appendix D for the details of registers,and in addition, refer to Table D- 1 for the description of "Attrib" in this specification.It is recommended for Host to use INQUIRY_CONFIG (whose initial values are set to Host'scapabilities) and SET_COMMON_CONFIG regardless of topology (P2P or Ring). Refer to Section6.2.8.3 for the details of INQUIRY_CONFIG and SET_COMMON_CONFIG. For each Capabilitiesregister, the operation is defined when receiving INQUIRY_CONFIG. Note that no operations take placeto the Capabilities field whose "Attrib" is Rsvd when receiving INQUIRY_CONFIG.The followings are Device behavior when written to the register whose "Attrib" is RO or HwInit. P2P CCMD Write: Device shall issue RES with NACK=0 and bit value of such register is notchanged. Broadcast CCMD Write: Device shall forward broadcast CCMD to the next node, and bit valuesuch register is not changed.A part of Section 6.2.9.2 is a blank in the Simplified Addendum.64
