5.2.16 PIN STRAP DISABLES
This setting disables the external pin configuration straps on power-up that select the following on ports 1-4:
• Port Disable
• Port Non-Removable
• Battery Charging Enable
If the user needs to select the above settings in a configuration file for ports 1-4, they must also disable the pin straps
to ensure the settings are not overridden by the strap controls.
5.2.17 PORT POWER/OCS CONTROL
5.2.17.1 Per-Port PWR/OCS Combined Mode
This per-port setting controls whether the Power Enable and OCS signals are on the same pin. This setting is only valid
for ports 1-4.
Refer to Section 4.4, "Standard Port Power Configuration," on page 20 for additional port power setting details and con-
nection diagrams.
5.2.17.2 OCS Gang Control
This setting can gang multiple ports into an OCS ganging to report overcurrent on any port in this gang.
ALL GANGED
This single setting configures all ports into an OCS gang.
SPLIT GANGED
This setting allows the user to gang select ports together while not ganging others.
Requires the setting of the following:
• USB 2.0 hub OCS gang set
• USB 3.0 hub OCS gang set
• Ports contained within the OCS gang (any other ports will operate as a per-port power control/ocs)
• GPIO used as OCS Gang input
