Purpose : Implementation of SEGGER real-time terminal which allows
          real-time terminal 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.

// Define SEGGER_RTT_IN_RAM as 1
// when using RTT in RAM targets (init and data section both in RAM).
// This prevents the host to falsly identify the RTT Callback Structure
// in the init segment as the used Callback Structure.
//
// When defined as 1,
// the first call to an RTT function will modify the ID of the RTT Callback Structure.
// To speed up identifying on the host,
// especially when RTT functions are not called at the beginning of execution,
// SEGGER_RTT_Init() should be called at the start of the application.
