7.3.2 USB Power Management
The TUSB8042A can be configured for power switched applications using either per-port (Full power
managed) or ganged power-enable controls and overcurrent status inputs. When battery charge is enabled,
the TUSB8042A always functions in full power managed.
Power switch support is enabled by REG_5h (fullPwrMgmtz) and the per-port or ganged mode is configured by
REG_5h (ganged).
The TUSB8042A supports both active high and active low power-enable controls. The PWRCTL[4:1] polarity is
configured by REG_Ah (pwrctlPol). The power control polarity can also be selected by the PWRCTL_POL pin.
