Hello,this is Lee.I have a problem about nRF51822.
When I turn on/off the power 2.8V to it ,it hangs up
frequently.I check POR function,I found that the residual
voltage (VDD) decreases slowly and stop at 0.5V.I doubt that
the residual voltage (VDD=0.5) cause nRF51822 not to be reseted and hangup.
when the VDD powers on angain,POR doesn't function and nRF51822 isn't running.
I don't know why? 1,the residual voltage(VDD=0.5)? 2,the power's noise? What is the casue of the nRF51822's halted (or hang_up)?
