CPU string
The instruction set can be specified in the source file with
the CPU pseudooperation. The string, delimited by quotes or
apostrophes, is scanned for a substring which selects which
instruction set is used. When the program is invoked, this
operation is performed on the name of the program, then the
-p optional arguement, if any, and then any CPU statements.
The last one selects which subset of the instructions the
assembler will accept. The instruction set can be changed
at any place in the source file.

DIRECT The direct addressing mode can be
used if the expression has a value
between 0 and 255. The expression
will be treated as a two byte long
value if it is not defined when the
statement is processed in the first
pass.
EXTENDED The expression can be a 2 byte long
value.
- 8 -
INDEX0 The Indexed addressing mode with no
offset can be used.
INDEX1 The Indexed addressing mode with a
one byte offset can be used.
INDEX2 The Indexed addressing mode with
two byte offset can be used.
INSTSTWA The instruction is only available
in the 146805, 6305, and 68hc05
instruction sets.
INSTMUL The instruction is only available
in the 68hc05 instruction set.
INSTDAA The instruction is only available
in the 6305 instruction set.
A.2.3 _✓A_✓p_✓o_✓s_✓t_✓r_✓o_✓p_✓h_✓e_✓s The apostrophes in the syntax field are

A.3.1 _✓B_✓i_✓t__✓N_✓u_✓m_✓b_✓e_✓r_✓s The bit number expression in the BSET,
BCLR, BRCLR, BRSET operations has to have value defined when
the instruction is read in the first pass. The value must
be between 0 and 7.
A.3.2 _✓I_✓n_✓d_✓e_✓x_✓e_✓d__✓A_✓d_✓d_✓r_✓e_✓s_✓s_✓i_✓n_✓g The indexed addressing mode is
represented in two ways.
First, with no offset, the form ",X" is used.
Second, the form "expression, X" is used for both the one
and two byte offsets modes. The expression will be treated
as a two byte long value if it is not defined when the
statement is processed in the first pass.
