For each of the 16 interfaces there is a 16-bit register that contains a status value which
is transmitted to the USB host upon a Get_Status request (figure 22-25).
For setting the Interface Get Status Register (IGSR) for a specific interface, the µC first
selects the interface number in the Interface Select Register (IFCSEL) and then writes
the status value for the corresponding interface to IGSR. The status value itself
(contained in IGSR) is fully specified by the USB spec. There is no function defined for
that yet in USB V1.1 (as of 09.99), however the device fully supports the Get_Status
request for potential changes in future.
