3.11 Battery current consumption monitor
KE770use 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 KE770mass 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)
