Host Requests
SetFeature PORT_RESET
Reinitialize the embedded function and set the Reset Change bit to indicate that the reset has completed. Reset the Enable Status bit, enable
the embedded function and set its address to 0 by the Set embedded function Address / Enable command. Disable the embedded function
interrupt endpoint by the Set Endpoint Enable command.
SetFeature PORT_ENABLE
Enable the function by the Set embedded function Address / Enable command. Set the Enable Status bit.
SetFeature PORT_SUSPEND
Disable the function by the Set embedded function Address / Enable command. Reset the Enable Status bit and set the Suspend Status bit.
ClearFeature PORT_ENABLE
Disable the function by the Set embedded function Address / Enable command. Reset the Enable Status bit.
ClearFeature PORT_SUSPEND
Enable the function by the Set embedded function Address / Enable command. Set the Enable Status bit, reset the Suspend Status bit; set the
Resume Status Change bit to indicate that the resume has completed.
ClearFeature any Change Indicator
Clear the corresponding status change bit.
Babbling Condition
When the embedded function causes a babbling condition, the function is automatically disabled by the PDIUSBH11. As soon as the micro
controller detects the babbling error, it must set the Enable Status Change bit and reset the Enable Status bit.
Remote WakeUp
There are three scenarios a remote wakeup can occur. The following describes the course of actions for each of the cases:
1. The device is not suspended and the embedded port is suspended
– Enable back the function by setting the enable bit in the Set Address/Enable register and update the following status bits in the
micro–controller program: reset the Suspend Status bit, set the Enable Status bit and set the Suspend Status Change bit.
2. The device is suspended and the embedded port is suspended.
– Send an upstream Resume using the Send Resume command, enable back the function by setting the enable bit in the Set
Address/Enable register and update the following status bits in the micro–controller program: reset the Suspend Status bit, set the Enable
Status bit and set the Suspend Status Change bit.
3. The device is suspended and the embedded port is enabled
– Send an upstream resume using the Send Resume command
