@section xc16x Machine Directives
16
 
17
The xc16x version of the assembler supports the following machine
18
directives:
19
 
20
@table @code
21
@cindex @code{align} directive, xc16x
22
@item .align
23
This directive aligns the section program counter on the next 2-byte
24
boundary.
25
 
26
 
27
@cindex @code{byte} directive, xc16x
28
@item .byte @var{expr}
29
This directive assembles a half-word (8-bit) constant.
30
 
31
@cindex @code{word} directive, xc16x
32
@item .word @var{expr}
33
This assembles a word (16-bit) constant.
34
 
35
@cindex @code{ascii} directive, xc16x
36
@item .ascii "@var{ascii}"
37
This directive used for copying @var{str} into the object file.
38
The string is terminated with a null byte.
39
 
40
@cindex @code{set} directive, xc16x
41
@item .set @var{symbol}, @var{value}
42
This directive creates a symbol named @var{symbol} which is an alias for
43
another symbol (possibly not yet defined).  This should not be confused
44
with the mnemonic @code{set}, which is a legitimate xc16x instruction.
45
 
46
 
47
 
48
@cindex @code{bss} directive, xc16x
49
@item .bss @var{symbol}, @var{length}
50
Reserve @var{length} bytes in the bss section for a local @var{symbol},
51
aligned to the power of two specified by @var{align}.  @var{length} and
52
@var{align} must be positive absolute expressions.  This directive
53
differs from @samp{.lcomm} only in that it permits you to specify
54
an alignment.
55
@end table
