		Enable RX handling mode which is switching buffers on timeout. This is an
		enhancement compared to other two modes (default and hardware assisted).

		If default driver uses interrupts to count incoming bytes, it is possible
		that with higher speeds and/or high cpu load some data can be lost.
		It is recommended to use hardware byte counting in such scenarios.
		Hardware RX byte counting requires timer instance and one PPI channel.

		This options is deprecated. Use UART_NRFX_UARTE_ENHANCED_RX which supports
		reliable byte counting without additional HW resources (TIMER and (D)PPI).
