If a host or power source is
connected to the TARGET Micro-B USB connector while no host is connected to the
DEBUG USB connector, then the Power Debugger
will be partly powered through the TARGET Micro-B connection and the POWER LED
will Flash. It is always recommended to plug a host to the DEBUG USB connector
before plugging anything to the TARGET Micro-B USB connector.
If a voltage is applied to the
EVT pin on the 20-pin DGI header while no host is connected to the DEBUG USB
connector, a current of up to 25 mA might flow into the EVT pin. It is always
recommended to plug a host to the DEBUG USB connector before applying any
voltage to any of the Power Debugger pin header
pins.
Running current measurements in
Data Visualizer while programming or debugging at low interface frequencies/baud
rates might result in Data Visualizer disconnecting from the Power Debugger. The lower limit of the interface
speed varies depending on target type, Flash size, and interface type, but is
typically in the range 100-300 kHz. In general, it is not recommended to measure
current while debugging as the current consumption will be affected by the
on-chip debug system on the target.
