Clear Status
Table 4-6.
Each time the device detects and reports an error indication status to the host in response to a
DFU_GETSTATUS request, it enters the dfuERROR state. After reporting any error status, the
device can not leave the dfuERROR state, until it has received a DFU_CLRSTATUS request.
Upon receipt of DFU_CLRSTATUS, the device sets status to OK and move to the dfuIDLE state.
Once the device is in the dfuIDLE state it is then able to move to other states.
