.align directive argument default = ?

RKMA

Friends,

1) I'm programming in assembly using the .align directive. If I just say ".align" without an argument, what will result?

2) Can I use a large argument, e.g., 2048d? (I'm using bk circular addressing.)

Targets: TMS320 '5402, '5407, '5409.

IDE and Tools: CCS v2.2 (code generation tools 3.83), CCS v3.3 (code generation tools v4.2.1) and CCS v4.0 (code generation tools v4.2.1).

Emulation: I create COFF (2?) files which are downloaded into the target via a Spectrum Digital emulator.

Thanks,

:) Robert

According to the TMS320C54x Assembly Language Tools User's Guide (revision F), section 4.5 "Directives That Align the Section Program Counter", using ".align" with no argument means ".align 128", and ".align" accepts "a power of 2 between 2^0 and 2^16 (although directives beyond 2^7 are not meaningful)." This is a bit misleading; the legal range is actually 1 to 32768, inclusive. These values are specific to C54x; other targets have different default alignment.

Archeologist,

Thanks very much for your response! The help files attached to the IDEs don't include this info, and maybe this is because of the target specifivity...
