DESCRIPTION

DEFAULT
7:0
Port Disable Self-Powered (PORT_DIS_SP)
Disables 1 or more ports.
0 = port is available
1 = port is disabled
During Self-Powered operation, when PRTMAP_EN = '0', this selects the
ports which will be permanently disabled, and are not available to be
enabled or enumerated by a Host Controller. The ports can be disabled in
any order, the internal logic will automatically report the correct number of
enabled ports to the USB Host, and will reorder the active ports in order to
ensure proper function.
When using the internal default option, the PRT_DIS[1:0] pins will disable
the appropriate ports.
