Hi premji

This thread provides some info

The first and second revision hardware of nRF51 has some current consumption issues with GPIOTE->IN (sensing signals from a GPIO pin) and GPIOTE->OUT (controlling GPIO pin). The third revision hardware has a solution for the GPIOTE->OUT tasks, but GPIOTE->IN is still high current. For input signal sensing on GPIO, use the GPIOTE->PORT event instead of GPIOTE->IN.

for information on chip revision, check the nrf51 compatibility matrix
