CONFIG_UART_1_NRF_HW_ASYNC
¶
Use hardware RX byte counting
Type: bool
Help¶
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
Direct dependencies¶

&& UART_1_NRF_UARTE
&& UART_NRFX
&& SERIAL
(Includes any dependencies from ifs and menus.)
Defaults¶
No defaults. Implicitly defaults to n
