This field is a 15-element nibble array, and each 4 bits is one array element. Each array
location corresponds one-to-one with a physical port provided by the Host Controller. For
example, PORTROUTE[0] corresponds to the first PORTSC port, PORTROUTE[1] to the
second PORTSC port, and so on. The value of each element indicates to which of 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.
The USB Command (USBCMD) register indicates the command to be executed by the
serial Host Controller. Writing to this register causes a command to be executed.
