Directives Reference.data/.dsSyntax.data.ds [address]DescriptionThe .data and .ds directives tell the assembler to begin assembling source codeinto data memory. The .data and .ds sections are normally used to contain tablesof data or preinitialized variables.address is an optional parameter that specifies a 16-bit address. Normally, thesection program counter is set to 0 the first time the .data or .ds section isassembled; you can use this parameter to assign an initial value to the SPC.Note that the assembler assumes that .text is the default section. Therefore,at the beginning of an assembly, the assembler assembles code into the .textsection unless you specify a section control directive.ExampleThis example shows the assembly of code into the .data and .text sections..ps 0a00h ;set up load and run addresses.entry.include ”VECT.ASM”.ds 0400h.textsetup: mar *,AR0 ;initialize the CPU registerslar AR0,#0lar AR1,#0lar AR2,#0lar AR3,#0val_1:.data.int 0,1,2,3,4,5,6,7 ;init. integer values.textloop: mar *+,AR1mar *+,AR2mar *+,AR3b loop,*+,AR0;continue with some codeval_2:.data.float 0,1,2,3,4,5,6,7 ;init. flt–pt valuesAssembler Directives5-15
