Figure 11: DFU Request Sub-frame Is Activated after a DFU Device Has Been Selected

2.1.8.2 DFU Requests Sub-frame

A smart card reader that has transitioned into the DFU mode is referred as a DFU device by the host

application program. The DFU Requests sub-frame is enabled only after a DFU device in the Card

Reader list box has been selected. This sub-frame contains five buttons each of which, when clicked,

causes a particular DFU command to be sent to the DFU device. These DFU requests are:

DFU_DNLOAD (DFU Download), DFU_GETSTATUS, DFU_CLRSTATUS (DFU Clear Status),

DFU_GETSTATE, and DFU_ABORT.
