Emulation running : it means a emulation is under execution. To avoid damaging a target microcontroller, please do not remove each cables at this state. Flash ROM writing : it means the state of nanoEASE is writing contents into the Flash ROM. To avoid damaging a target microcontroller, please do not remove each cables at this state. Detected illegal input voltage on VTref port : it means the supplied voltage on VTref port of nanoEASE is not within the guaranteed range of nanoEASE. Please confirm connections and their restrictions between nanoEASE and user target board, and check the voltage level of power supply on a user target board. Failed the recognition of device driver : It means the host PC cannot recognize nanoEASE connected to host PC with the USB cable. Please install a device driver according to the dialog displayed on host PC. Command execution error : it means the state of command response from a target microcomputer to nanoEASE is not normal. Please confirm whether there is any problem in the connection state of a user target system and nanoEASE, and a command operating procedure. nanoEASE failure : It means the nanoEASE may be out of order. Continued use risks fire and electrical shock. Please extract immediately the USB cable connected to nanoEASE, and separate all external power cords. Please contact a distributor, when you cannot discover a problem in the connection state of nanoEASE and a user target system, and the connection state of nanoEASE and a USB cable. 20 4 Notes 4 Notes 4.1 About cables Be sure to use the accessories provided.
