The field is 32 bits, the
destination
The field is not generated by buildtask, it is generated by the assembler (usually as an IMEM
label).
At run time, the DRAM address of the microcode object (part of the OSTask structure) must be added to the
offset
field to generate the correct DRAM address for each overlay.
Data objects for subsequent overlays may be redundant and need not be used. The -f argument can be used to
ignore these data sections.
