This anomaly applies to IC Rev. Engineering B, build codes QFAA-BA0, CHAA-AA0.
Static current consumption between 400 µA to 450 µA when using TWI in combination with GPIOTE.
Current consumption higher than specified
*(volatile uint32_t *)0x40003FFC = 0;
*(volatile uint32_t *)0x40003FFC;
*(volatile uint32_t *)0x40003FFC = 1;
If TWI1 is used,
*(volatile uint32_t *)0x40004FFC = 0;
*(volatile uint32_t *)0x40004FFC;
*(volatile uint32_t *)0x40004FFC = 1;
write 0 followed by a 1 to the POWER register (address 0xFFC) of the TWI that needs to be disabled. Reconfiguration of TWI is required before next usage.
