Will Gpiote increase the current comsuption?

[kk]

Hi all!

I'm running my code based on example "ble_app_template". When advertising without doing anything else, the current comsuption is about 200 uA.

Then I added a GPIOTE event for a button(in order to go into sleep mode when pressing the button), then the current comsuption rised to 1.2 mA.

the code is :

NRF_GPIOTE->CONFIG[1] = (GPIOTE_CONFIG_POLARITY_HiToLo <<GPIOTE_CONFIG_POLARITY_Pos)| (3 << GPIOTE_CONFIG_PSEL_Pos) | (GPIOTE_CONFIG_MODE_Event <<GPIOTE_CONFIG_MODE_Pos);

NRF_GPIOTE->INTENSET =GPIOTE_INTENSET_IN1_Set <<GPIOTE_INTENSET_IN1_Pos;

And my understanding is: As what i have been told, the current comsuption about 1mA might be caused by the 16MHz clock, does is mean the code aboved open the 16MHz clock?

I'm really confused about this problem, looking forward to your reply!

If what i said above is not clear, i just want to ask: what does the GPIOTE Event Mode need? (16MHz clock? or anything else that could cause current consumption increasement)

this post raised the same qusetion as mine, but still unsolved. Looking forward to your reply!

I think I find my solution here, devzone.nordicsemi.com/.../ thank you for watching anyway!
