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