Purpose : Implementation of SEGGER real-time transfer (RTT) which
allows real-time communication on targets which support
debugger memory accesses while the CPU is running.

// Target is not allowed to perform other RTT operations while string still has not been stored completely.
// Otherwise we would probably end up with a mixed string in the buffer.
// If using RTT from within interrupts, multiple tasks or multi processors, define the SEGGER_RTT_LOCK() and SEGGER_RTT_UNLOCK() function here.
