Full power management is the ability to control power to the downstream ports of the TUSB8041-Q1 using PWRCTL[4:1]/BATEN[4:1].
When SMBus mode is enabled using SMBUSz, this pin sets the value of the SMBus slave address bit 1.
Can be left unconnected if full power management and SMBus are not implemented.
After reset, this signal indicates the SuperSpeed USB connection status of the upstream port if enabled through the Additional Feature Configuration register. When enabled a value of 1 indicates the upstream port is connected to a SuperSpeed USB capable port.
Note: Power switching must be supported for battery charging applications.

The value of the pin is sampled at the de-assertion of reset to set the power switch and over current detection mode as follows:
0 = Individual power control supported when power switching is enabled
1 = Power control gangs supported when power switching is enabled
When SMBus mode is enabled using SMBUSz, this pin sets the value of the SMBus slave address bit 2.
After reset, this signal indicates the High-speed USB connection status of the upstream port if enabled through the Additional Feature Configuration register. When enabled a value of 1 indicates the upstream port is connected to a High-speed USB capable port.

The value of the pin is sampled at the de-assertion of reset to determine if automatic mode is enabled as follows:
0 = Automatic Mode is enabled on ports that are enabled for battery charging when the hub is unconnected. Please note that CDP is not supported on Port 1 when operating in Automatic mode.
1 = Automatic Mode is disabled
This value is also used to set the autoEnz bit in the Battery Charging Support Register.
