How to get low power If I using GPIOTE IN events in nRF51822?

[premji]

As I am using four GPIOTE IN events to get interrupt on gpio-pin's rising-edge, please let me know whether it is possible to get low power or not.

If not, please show me alternate way.

Thanks.

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
