 * Are comments and documentation written in clear English, with no spelling or grammar errors?
 
+* Example contributions are also welcome. Please check the :doc:`creating-examples` guide for these.
+
 * If the contribution contains multiple commits, are they grouped together into logical changes (one major change per pull request)? Are any commits with names like "fixed typo" `squashed into previous commits <http://eli.thegreenplace.net/2014/02/19/squashing-github-pull-requests-into-a-single-commit/>`_?
 
 * If you're unsure about any of these points, please open the Pull Request anyhow and then ask us for feedback.

+// SEGGER_RTT_MAX_INTERRUPT_PRIORITY can be used in the sample lock routines on Cortex-M3/4.
+// Make sure to mask all interrupts which can send RTT data, i.e. generate SystemView events, or cause task switches.
+// When high-priority interrupts must not be masked while sending RTT data, SEGGER_RTT_MAX_INTERRUPT_PRIORITY needs to be adjusted accordingly.

+// Default value for embOS: 128u
+// Default configuration in FreeRTOS: configMAX_SYSCALL_INTERRUPT_PRIORITY: ( configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY << (8 - configPRIO_BITS) )
+// In case of doubt mask all interrupts: 1 << (8 - BASEPRI_PRIO_BITS) i.e. 1 << 5 when 3 bits are implemented in NVIC
+// or define SEGGER_RTT_LOCK() to completely disable interrupts.
