80 >&#13;The following options for displaying cycle counts in listings are provided.
81 These options are enabled from pragmas on the command line or in the
82 assembly files themselves. For compatibility with other assemblers you can
83 use the "OPT" keyword in addition to "PRAGMA."</P

87 opt cd - enable detailed cycle counts breaking down addressing modes: [5+3]

89 opt cc - clear the running subtotal</PRE

91 >&#13;The assembler supports both 6809 as well as native-mode 6309 cycle counts.
92 In 6309 mode the counts are displayed in parenthesis instead of brackets.
93 In addition, some operations have a variable cycle count. In this case a
94 "+?" is displayed to alert the reader. Sample output is shown below.</P
