Note
：
1. Since the CMT2310A-EM board is equipped with reserved Current Detect jumper terminals, the current
consumption under sending packet mode of CMT2310A can be tested by combining this mode.
However,
in this sending mode, the current will be fluctuated and not stable for the reason that there will be a brief
intermittent between sending packets arising from standby mode.
2. In the process of sending a packet, LED1 flickers, and its flickering rhythm is related to the packet
consumption time. When it pauses or exits from Tx, LED1 will be extinguished accordingly.
