6.1 Using the DSK Assembler Directives
Table 6–1 summarizes the assembler directives. Note that all source state-
ments that contain a directive may have a label and a comment. To improve
readability, they are not shown as part of the directive syntax.
Table 6–1. Assembler Directives Summary
(a) Directives that define sections
Mnemonic and Syntax Description Page

.sect ” section name” Assemble source code into a named (initialized) sec-
tion 6-27
.text Assemble source code into program memory 6-32
