Directives Reference.mmregsSyntaxDescription.mmregsThe .mmregs directive defines global symbolic names for the TMS320 registersand places them in the global symbol table. It is equivalent to executinggreg .set 5, imr .set 4, etc. The symbols are local and absolute. Using the.mmregs directive makes it unnecessary to define these symbols. Thesymbols are placed as shown in Table 5–2.Table 5–2.
