- **Pattern detection**: An interrupt triggered on detecting a 'pattern' of the same character being received/sent repeatedly for a number of times. This functionality is demonstrated in the example :example:`peripherals/uart/uart_events`. It can be used, e.g., to detect a command string followed by a specific number of identical characters (the 'pattern') added at the end of the command string. The following functions are available:
- Configure and enable this interrupt using :cpp:func:`uart_enable_pattern_det_intr`
- Configure and enable this interrupt using :cpp:func:`uart_enable_pattern_det_baud_intr`
- Disable the interrupt using :cpp:func:`uart_disable_pattern_det_intr`
