.mmregs
Assign Memory–Mapped Register Names as Global Symbols
Syntax
Description
Table 4–2. Memory-Mapped Registers
4-70
.mmregs
The .mmregs directive defines global symbolic names for the 'C54x registers
and places them in the global symbol table. It is equivalent to executing AL .set
8, AH .set 9, etc. The symbols are local and absolute. Using the .mmregs direc-
tive makes it unnecessary to define these symbols.

Note: Duplication of address values in the table supports the different names of the registers
as they are implemented on different 'C54x devices.
