When TWI0 and GPIOTE are turned on at the same time, the power consumption will increase by 500uA

Hi:

 PREJECT: nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_hrs_freertos\pca10040\s132\arm5_no_packs

 When TWI0 and GPIOTE are turned on at the same time,
the power consumption will increase by 500uA,
and the power consumption of TWI and GPIOTE alone will be normal.

 help  me please ！！

//TWI INIT
twi_master_init();

//GPIOTEINI
if(!nrf_drv_gpiote_is_init())
{
err_code=nrf_drv_gpiote_init();

APP_ERROR_CHECK(err_code);

}
nrf_drv_gpiote_in_config_t in_config=GPIOTE_CONFIG_IN_SENSE_HITOLO(true);
err_code=nrf_drv_gpiote_in_init(27,&in_config,int1pin_gpiote);
APP_ERROR_CHECK(err_code);
nrf_drv_gpiote_in_event_enable(27,true);

Hi jermi

This is known problem. You can solve this problem by following this link (http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.EngB.errata%2Fanomaly_832_89.html).

I solve this problem by uniniting TWI after the communication finish. Like this;

nrf_drv_twi_uninit(&m_twi);
*(volatile uint32_t *)0x40003FFC = 0;
*(volatile uint32_t *)0x40003FFC;
*(volatile uint32_t *)0x40003FFC = 1;
