Battery Current Consumption Monitor; Jtag & Etm Interface Connector - LG KF600d Service Manual

3. TECHNICAL BRIEF

3.11. Battery current consumption monitor

KF600 use a current monitoring function to calculate the battery capacity and the remaining time, as
monitoring current flow from the battery thru 47mohm resistor.
3.12. JTAG & ETM interface connector
Figure 18 JTAG & ETM(Embedded Trace Module) interface connector
In case of KF600 mass production, the JTAG & ETM interface connector will not be mount on board.
That is only for developing and software debugging purpose.( It will not be mounted on mass
production PCB)
