  • R
    Register hcsparams reader

Type Aliases§

  • DEBUG_PORT_NUMBER_R
    Field debug_port_number reader - This register identifies which of the host controller ports is the debug port. The value is the port number (one based) of the debug port.
  • N_CC_R
    Field n_cc reader - Number of Companion Controller (N_CC)
  • N_PCC_R
    Field n_pcc reader - Number of Port per Companion Controller (N_PCC)
  • N_PORTS_R
    Field n_ports reader - This field specifies the number of physical downstream ports implemented on this host controller. The value of this field determines how many port registers are addressable in the Operational Register Space. Valid values are in the range of 0x1 to 0x0f.
  • PORT_ROUTING_RULES_R
    Field port_routing_rules reader - This field indicates the method used by this implementation for how all ports are mapped to companion controllers.
