| help |
| Enable GPIO edge interrupts implementation using GPIO SENSE, which is |
| a level interrupt mechanism. Conversion from level to edge interrupts |
| notification happens in GPIO driver, so it is transparent to GPIO |
| consumers after switching from GPIOTE mechanism. |
| |
| Use this option as an alternative to GPIOTE event mechanism. According |
| to product specifications and erratas to some nRF MCUs, using GPIOTE |
| results in increased current consumption in System ON Idle and in |
| conjunction with SPI/TWI peripherals. Selecting this option allows to |
| reduce current for those cases. |
| |
| Using this option additionally allows detecting state changes of pins |
| configured as output, which might be handy for some applications. |
