3.7.1. Asm68k Section Directives
Section directives can be used to manage both absolute and relocatable sections
with any of the following types: text-type, data-type, or BSS-type. Text-type
sections contain read-only data. Data-type sections contain initialized read/write
data. BSS-type sections contain uninitialized read/write data. Section directives
remain in effect until another section directive is issued.
Section directives can also be used to create structure template sections; these
are special dummy sections that allow the convenient definition of labels suitable
for structure field references. Table 3.24 summarizes the section directives for
asm68k
. For more information, see section
3.3.4 Sections
. See chapter
7. Flash Application Layout
in the TI-89 / TI-92 Plus Developer Guide for
information on the use and initialization of the TI-89 / TI-92 Plus sections.
