The document indicates that the RTX requires minimun 450 Bytes XDATA, What could be the maximum for a small application and What should be taking care in order to minimize the XDATA usage. I have created a application that includes one fast task and one normal task. Following is M51 file which shows that almost 900 bytes are allocated to RTX. Is there anything I can do to reduce it? * * X D A T A M E M O R Y * * * * XDATA 0000H 0100H PAGE ?RTX?RTX_MBX_PAGE XDATA 0100H 0100H INPAGE ?RTX?RTX_AUX_PAGE XDATA 0200H 00F4H INPAGE ?RTX?RTX_SYS_PAGE XDATA 0300H 0080H PAGE ?RTX?RTX_SEM_PAGE
