80 >LWASM supports all documented MC6809 instructions as defined by Motorola.
|
|
|
81 It also supports all known HD6309 instructions. While there is general
|
|
|
82 agreement on the pneumonics for most of the 6309 instructions, there is some
|
|
|
83 variance with the block transfer instructions. TFM for all four variations
|
|
|
84 seems to have gained the most traction and, thus, this is the form that is
|
|
|
85 recommended for LWASM. However, it also supports COPY, COPY-, IMP, EXP,
|
|
|
86 TFRP, TFRM, TFRS, and TFRR. It further adds COPY+ as a synomym for COPY,
|
|
|
87 IMPLODE for IMP, and EXPAND for EXP.</P

|
|
|
89 >By default, LWASM accepts 6309 instructions. However, using the

90 <CODE
|
|
|
91 CLASS="PARAMETER"
|
|
|
92 >--6809</CODE
|
|

|
|
|
94 6309 instructions instead.</P
|
|
|
95 ><P
|
|
|
96 >The standard addressing mode specifiers are supported. These are the
|
|
|
97 hash sign ("#") for immediate mode, the less than sign ("<") for forced
|
|
|
98 eight bit modes, and the greater than sign (">") for forced sixteen bit modes.</P
|
|
|
99 ><P
|
|
|
100 >Additionally, LWASM supports using the asterisk ("*") to indicate
|
|
|
101 base page addressing. This should not be used in hand-written source code,
|
|
|
102 however, because it is non-standard and may or may not be present in future
|

103 versions of LWASM.</P
