+@section Syntax
+
+@cindex S12Z syntax
+@cindex syntax, S12Z
+
+In the S12Z syntax, the instruction name comes first and it may
+be followed by one or by several operands.
+In most cases the maximum number of operands is three.
+Some instructions accept and (in certain situations require) a suffix
+indicating the size of the operand.
+The suffix is separated from the instruction name by a period (@samp{.})
+and may be one of @samp{b}, @samp{w}, @samp{p} or @samp{l} indicating
+`byte' (a single byte), `word' (2 bytes), `pointer' (3 bytes) or `long' (4 bytes)
+respectively.
+Operands are separated by a comma (@samp{,}).
+A comma however does not act as a separator if it appears within parentheses
+(@samp{()}) or within square brackets (@samp{[]}).
+@code{@value{AS}} will complain if too many, too few or inappropriate operands
+are specified for a given instruction.
+The MRI mode is not supported for this architecture.
+Example:
+
+@smallexample
+	bset.b  0xA98, #5
+	mov.b   #6, 0x2409
+	ld      d0, #4
+	mov.l   (d0, x), 0x2409
+	inc     d0
+	cmp     d0, #12
+	blt     *-4
+	lea     x, 0x2409
+	st      y,  (1, x)
+@end smallexample
+
+@cindex line comment character, S12Z
+@cindex S12Z line comment character
+The presence of a @samp{;} character anywhere
+on a line indicates the start of a comment that extends to the end of
+that line.
+
+A @samp{*} or a @samp{#} character at the start of a line also
+introduces a line comment, but these characters do not work elsewhere
+on the line.  If the first character of the line is a @samp{#} then as
+well as starting a comment, the line could also be logical line number
+directive (@pxref{Comments}) or a preprocessor control command
+(@pxref{Preprocessing}).
+
+@cindex line separator, S12Z
+@cindex statement separator, S12Z
+@cindex S12Z line separator
+The S12Z assembler does not currently support a line separator
+character.
+
+@cindex S12Z addressing modes
+@cindex addressing modes, S12Z
+The following addressing modes are understood for the S12Z.
+@table @dfn
+@item Immediate
+@samp{#@var{number}}
+
+@item Immediate Bit Field
+@samp{#@var{width}:@var{offset}}
+
+Bit field instructions in the immediate mode require the width and offset to
+be specified.
+The @var{width} pararmeter specifies the number of bits in the field.
+It should be a number in the range [1,32].
+@var{Offset} determines the position within the field where the operation
+should start.
+It should be a number in the range [0,31].
+
+@item Relative
+@samp{*@var{symbol}}, or @samp{*[+-]@var{digits}}
+
+Program counter relative addresses have a width of 15 bits.
+Thus, they must be within the range [-32768, 32767].
+
+@item Register
+@samp{@var{reg}}
+
+Some instructions accept a register as an operand.
+In general, @var{reg} may be a data register (@samp{D0}, @samp{D1} @dots{}
+@samp{D7}), the @var{X} register or the @var{Y} register.
+
+A few instructions accept as an argument the stack pointer
+register (@samp{S}), and/or the program counter (@samp{P}).
+
+Some very special instructions accept arguments which refer to the
+condition code register.  For these arguments the  syntax is
+@samp{CCR}, @samp{CCH} or @samp{CCL} which refer to the complete condition code register, the condition code register high byte and the condition code register low byte respectively.
+
+@item Absolute Direct
+@samp{@var{symbol}}, or @samp{@var{digits}}
+
+@item Absolute Indirect
+@samp{[@var{symbol}}, or @samp{@var{digits}]}
+
+
+@item Constant Offset Indexed
+@samp{(@var{number},@var{reg})}
+
+@var{Reg} may be either @samp{X}, @samp{Y}, @samp{S} or
+@samp{P} or one of the data registers @samp{D0}, @samp{D1} @dots{}
+@samp{D7}.
+If any of the registers @samp{D2} @dots{} @samp{D5} are specified, then the
+register value is treated as a signed value.
+Otherwise it is treated as unsigned.
+@var{Number} may be any integer in the range [-8388608,8388607].
+
+@item Offset Indexed Indirect
+@samp{[@var{number},@var{reg}]}
+
+@var{Reg} may be either @samp{X}, @samp{Y}, @samp{S} or
+@samp{P}.
+@var{Number} may be any integer in the range [-8388608,8388607].
+
+@item Auto Pre-Increment/Pre-Decrement/Post-Increment/Post-Decrement
+@samp{-@var{reg}},
+@samp{+@var{reg}},
+@samp{@var{reg}-} or
+@samp{@var{reg}+}
+
+This addressing mode is typically used to access a value at an address,
+and simultaneously to increment/decrement the register pointing to that
+address.
+Thus @var{reg} may be any of the 24 bit registers @samp{X}, @samp{Y}, or
+@samp{S}.
+Pre-increment and post-decrement are not available for
+register @samp{S} (only post-increment and pre-decrement are available).
+
+@item Register Offset Direct
+@samp{(@var{data-reg},@var{reg})}
+
+@var{Reg} can be either @samp{X}, @samp{Y}, or @samp{S}.
+@var{Data-reg}
+must be one of the data registers @samp{D0}, @samp{D1} @dots{} @samp{D7}.
+If any of the registers @samp{D2} @dots{} @samp{D5} are specified, then
+the register value is treated as a signed value.
+Otherwise it is treated as unsigned.
+
+@item Register Offset Indirect
+@samp{[@var{data-reg},@var{reg}]}
+
+@var{Reg} can be either @samp{X} or @samp{Y}.
+@var{Data-reg}
+must be one of the data registers @samp{D0}, @samp{D1} @dots{} @samp{D7}.
+If any of the registers @samp{D2} @dots{} @samp{D5} are specified, then
+the register value is treated as a signed value.
+Otherwise it is treated as unsigned.
+
+
+@end table
+
+For example:
+
+@smallexample
+	trap    #197
+	bra     *+49
+	bra     .L0
+	jmp     0xFE0034
+	jmp     [0xFD0012]
+	inc.b   (4,x)
+	dec.w   [4,y]
+	clr.p   (-s)
+	neg.l   (d0, s)
+	com.b   [d1, x]
+	jsr     (45, d0)
+	psh     cch
