nrf51822 reset

[jane xue]

I am using nrf51822 and having some questions,as follow: 1、the pin reset is common with the pin SWDIO(the debug IO pin).when I download into nrf51822 using JLINK（setting:program\verity\reset and run），the pin reset is not useful(reset is given low level pulse)。I have to cut off the battary and power-on again ,then the pin reset is useful.This is why?May I use the program to solve this problem?

Please see section 11.1.3 "Resuming Normal Mode" in the nRF51 series reference manual (from Resources tab above) which gives you the sequence to put the chip back into reset pin mode.
