-File    : SEGGER_RTT.c
-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.
-Revision: $Rev: 17697 $
-
-Additional information:
-          Type "int" is assumed to be 32-bits in size
-          H->T    Host to target communication
-          T->H    Target to host communication
-
-          RTT channel 0 is always present and reserved for Terminal usage.
-          Name is fixed to "Terminal"
-
-          Effective buffer size: SizeOfBuffer - 1
-
-          WrOff == RdOff:       Buffer is empty
-          WrOff == (RdOff - 1): Buffer is full
-          WrOff >  RdOff:       Free space includes wrap-around
-          WrOff <  RdOff:       Used space includes wrap-around
-          (WrOff == (SizeOfBuffer - 1)) && (RdOff == 0):  
-                                Buffer full and wrap-around after next byte

-*  Function description
-*    Stores a specified number of characters in SEGGER RTT

-*    SEGGER_RTT_WriteSkipNoLock does not lock the application and
-*    skips all data, if the data does not fit into the buffer.
-*
-*  Parameters
-*    BufferIndex  Index of "Up"-buffer to be used (e.g. 0 for "Terminal").
-*    pBuffer      Pointer to character array. Does not need to point to a \0 terminated string.
-*    NumBytes     Number of bytes to be stored in the SEGGER RTT control block.
-*                 MUST be > 0!!!
-*                 This is done for performance reasons, so no initial check has do be done.
-*
-*  Return value
-*    1: Data has been copied
-*    0: No space, data has not been copied
-*
-*  Notes
-*    (1) If there is not enough space in the "Up"-buffer, all data is dropped.
-*    (2) For performance reasons this function does not call Init()
-*        and may only be called after RTT has been initialized.
-*        Either by calling SEGGER_RTT_Init() or calling another RTT API function first.

-*       RTT memcpy configuration
-*
-*       memcpy() is good for large amounts of data, 
-*       but the overhead is big for small amounts, which are usually stored via RTT.
-*       With SEGGER_RTT_MEMCPY_USE_BYTELOOP a simple byte loop can be used instead.
-*
-*       SEGGER_RTT_MEMCPY() can be used to replace standard memcpy() in RTT functions.
-*       This is may be required with memory access restrictions, 
-*       such as on Cortex-A devices with MMU.
