-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.

-#define BUFFER_SIZE_DOWN                          (16)    // Size of the buffer for terminal input to target from host (Usually keyboard input) (Default: 16)

-// 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.
-//
-// 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.
-// (Higher priority = lower priority number)
-// 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.
-//
-
-#define SEGGER_RTT_MAX_INTERRUPT_PRIORITY         (0x20)   // Interrupt priority to lock on SEGGER_RTT_LOCK on Cortex-M3/4 (Default: 0x20)
