3.6 Registers
This section explains the types of register used by MP920 user programs and how these registers
are used.
3.6.1 Register Designation Methods
Registers can be designated by direct designation of the register number or by symbolic des-
ignation. These two types of register designation can be used together in the same user pro-
gram. When symbolic designation is used, the correspondence between the symbols and the
register numbers is defined in the symbol table that is described later.
Table 3.12 shows the register designation methods.
