nRF51822's twi & GPIOTE current is too Big.

[cw-park]

Hi.

After stopping the Advertising,I measured the current.

For some reason, usually it is consumes about 1.1mA.

Because too large current consumption,

As a result of looking for a specific location, and are as follows.

· GPIOTE CONFIG register (NRF_GPIOTE-> CONFIG) setting

· TWI of Enable (NRF_TWI1-> ENABLE)

If you enable the above two places,It will drop to up to about 0.7mA ~ 0.8mA.

Is this Correct? Please tell us why this is so. (You are referring to the nRF51822-PAN v2.3, but since the numbers reduced by the presence or absence of GPIOTE is different. I'm worried about. )

※ environment

· NRF51822 (2nd Revision - QFAAG00)

· SoftDevice - s110_nrf51822_7.0.0

· SDK - nrf51_sdk_v6_1_0_b2ec2e6

GPIOTE draws current if you are configuring it events or task mode, I don't remember the PAN number but check PAN for your revision. It does not draw too much current if you configure GPIOTE only in PORT mode.

Yes, GPIOTE was set to task mode. and Checked PAN v2.0(39.GPIOTE: 1V2 + HFCLK are requested always when the GPIOTE task is configured.)

Also, I had a problem with the GPIOTE
