Figure 10.2 – .ORG File
Figure 10.3 – .MAP File
The preceding .org file shows how much of an allocated range is actually used. In addition,
there is an information window that displays the total code size after each compile.
Data Space Management
There is about 756 K of total memory for data storage. Only a small portion of this data
space is in root memory. To increase the amount of data space in root memory, set the
directive ROOT_SIZE_4K to be equal to 0x1 using the Defines tab under Project Options.
The data not in the root block must be declared using the “far” prefix.
In the .org and .map files, physical addresses can be determined from logical address in-
formation. To do so, take the two digit value to the left of the colon and add three zeros to
the right of it. Then take the resulting five-digit value and add it to the four-digit value on
the right of the colon. For example, 10:b1bc translates to physical hex address 0x01 b1bc.
While the program is being debugged you can do a memory dump to look at the contents of
the data space. You can enter an address for the memory dump window the following three
