If you want to put a variable/array into SRAM or XDATA you can simply add xdata as prefix when you declare.</p> <p>For example: <code>xdata uint8_t payload[300];</code></p> <p>If you want to put everything in XDATA, you can select Large model. Then everything is slower as the CPU have to access SRAM.</p><div style="clear:both;"></div>
