Help¶

When enabled, UARTE is enabled before each TX or RX usage and disabled
when not used. Disabling UARTE while in idle allows to achieve lowest
power consumption. It is only feasible if receiver is not always on.

Direct dependencies¶

UART_0_NRF_UARTE && UART_ASYNC_API && (UART_0_NRF_UART || UART_0_NRF_UARTE) && UART_NRFX && SERIAL

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
