@section xc16x Machine Directives
|
||
|
|
|
||
|
|
The xc16x version of the assembler supports the following machine
|
||
|
|
directives:
|
||
|
|
|
||
|
|
@table @code
|
||
|
|
@cindex @code{align} directive, xc16x
|
||
|
|
@item .align
|
||
|
|
This directive aligns the section program counter on the next 2-byte
|
||
|
|
boundary.
|
||
|
|
|
||
|
|
|
||
|
|
@cindex @code{byte} directive, xc16x
|
||
|
|
@item .byte @var{expr}
|
||
|
|
This directive assembles a half-word (8-bit) constant.
|
||
|
|
|
||
|
|
@cindex @code{word} directive, xc16x
|
||
|
|
@item .word @var{expr}
|
||
|
|
This assembles a word (16-bit) constant.
|
||
|
|
|
||
|
|
@cindex @code{ascii} directive, xc16x
|
||
|
|
@item .ascii "@var{ascii}"
|
||
|
|
This directive used for copying @var{str} into the object file.
|
||
|
|
The string is terminated with a null byte.
|
||
|
|
|
||
|
|
@cindex @code{set} directive, xc16x
|
||
|
|
@item .set @var{symbol}, @var{value}
|
||
|
|
This directive creates a symbol named @var{symbol} which is an alias for
|
||
|
|
another symbol (possibly not yet defined). This should not be confused
|
||
|
|
with the mnemonic @code{set}, which is a legitimate xc16x instruction.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
@cindex @code{bss} directive, xc16x
|
||
|
|
@item .bss @var{symbol}, @var{length}
|
||
|
|
Reserve @var{length} bytes in the bss section for a local @var{symbol},
|
||
|
|
aligned to the power of two specified by @var{align}. @var{length} and
|
||
|
|
@var{align} must be positive absolute expressions. This directive
|
||
|
|
differs from @samp{.lcomm} only in that it permits you to specify
|
||
|
|
an alignment.
