The mnemonics for the
asm68
assembler directives, like those for instructions,
are written in either all uppercase or all lowercase characters. As stated earlier,
the mnemonics for
asm68
are shown in lowercase characters only to
differentiate them from those for
asm68k
, which are shown in uppercase
characters.
3.6.1. Asm68 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 3.17 summarizes the section directives for
asm68
. 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.
