View the official Windows Driver Kit DDI referenceNo description available.
The PHY_CONFIGURATION_PACKET structure contains a raw PHY configuration packet.
PCP_Phys_IDSpecifies the node address of the root. This member contains bits 0-5 of byte 0 of the packet.
PCP_Packet_IDThis member must be PHY_PACKET_ID_CONFIGURATION to indicate it is a PHY configuration packet. This member contains bits 6-7 of byte 0 of the packet.
PCP_Gap_CountIf the PCP_Set_Gap_Count bit is set, the PHY register gap_count field is set to this value. This member contains bits 0-5 of byte 1 of the packet.
PCP_Set_Gap_CountIf this bit is set, the PHY register gap_count field is set to PCP_Gap_Count. This member contains bit 6 of byte 1 of the packet.
PCP_Force_RootIf set, the caller becomes the root node. This member contains bit 7 of byte 1 of the packet.
PCP_Reserved1Reserved. This member contains bits 0-7 of byte 2 of the packet.
PCP_Reserved2Reserved. This member contains bits 0-7 of byte 3 of the packet.
PCP_InverseSpecifies the logical inverse of the first quadlet of the packet.
For an explanation of the function of the PHY configuration packet, see the IEEE 1394 specification.
