* 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. |
