HCSP_ORTROUTE Bits 31 : 0
R
0x0
This optional field is valid only if Port Routing Rules field in HCSPARAMS
register is set to a one.
This field is used to allow a host controller implementation to explicitly
describe to which companion host controller each implemented port is
mapped. This field is a 15-element nibble array (each 4 bit is one array element).
Each array location corresponds one-to-one with a physical port
provided by the host controller (e.g. PORTROUTE [0] corresponds to the first
PORTSC port, PORTROUTE [1] to the second PORTSC port, etc.). The value of
each element indicates to which the companion host controllers this port is
routed. Only the first N_PORTS elements have valid information. A value of
zero indicates that the port is routed to the lowest numbered function
companion host controller. A value of one indicates that the port is routed
to the next lowest numbered function companion host controller, and so on.
