+ * Symbols controlling behavior of this code...
+ *
+ * __MTB_DISABLE
+ *     If this symbol is defined, then the buffer array for the MTB
+ *     will not be created.
+ *
+ * __MTB_BUFFER_SIZE
+ *     Symbol specifying the sizer of the buffer array for the MTB.
+ *     This must be a power of 2 in size, and fit into the available
+ *     RAM. The MTB buffer will also be aligned to its 'size' 
+ *     boundary and be placed at the start of a RAM bank (which 
+ *     should ensure minimal or zero padding due to alignment).
+ * 
+ * __MTB_RAM_BANK
+ *     Allows MTB Buffer to be placed into specific RAM bank. When 
+ *     this is not defined, the "default" (first if there are 
+ *     several) RAM bank is used.
