Set Status Change Bits
Command
: F7h
Data
: Write 1 byte
For assembling the hub’s status change register, the device needs some additional information from the controller, i.e. the Local Power Status
Change bit and the embedded function Status Change bit.
These are provided by the Set Status Change Bits command. This command is always followed by one data write which contains the Local
Power Status Change bit at the LSB and the embedded function Status Change bit at position 1. All other bits should be 0.

GENERAL COMMANDS
Send Resume
Command
: F6h
Data
: None
Sends an upstream resume signal for 10 ms. This command is normally issued when the device is in suspend. The RESUME command is not
followed by a data read or write.
The PDIUSBH11 automatically sends a RESUME command when an event occurs downstream.
Read Current Frame Number
Command
: F5h
Data
: Read 1 or 2 bytes
This command is followed by one or two data reads and returns the frame number of the last successfully received SOF. The frame number is
returned Least Significant Byte first.

EMBEDDED FUNCTION
The USB host sees no difference between the embedded function and a function connected to one of the downstream ports. Some of the port
commands sent by the host must be handled appropriately by the embedded function to appear as any other downstream port.
The micro controller maintains a series of status and status change bits for the embedded function as described in the Get Port Status
command section. From these bits, the Status Change bit for the embedded function is derived (i.e. the port specific Status Change bits). This
Status Change bit is then provided to the PDIUSBH11 by the Set Status Change Bits command.
