I think the MAX current is too early for us, because the GTA02 has many
peripherals and these peripherals have many operating mode. Maybe the
talking time and standby time are important. Therefore, I suggest we
maybe fore on talking mode and standby mode.
Can we treat talking mode and standby mode as our fist target?
