3.11 Battery current consumption monitor
KE600/KE608 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
In case of KE600/KE608 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)
