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

112* RTT memcpy configuration

114* memcpy() is good for large amounts of data,
115* but the overhead is big for small amounts, which are usually stored via RTT.
116* With SEGGER_RTT_MEMCPY_USE_BYTELOOP a simple byte loop can be used instead.
117*
118* SEGGER_RTT_MEMCPY() can be used to replace standard memcpy() in RTT functions.
119* This is may be required with memory access restrictions,
120* such as on Cortex-A devices with MMU.
