The stack pointer associated with an operator will give an error if it occurs in the list. The registers can be D, X, Y, U, S, PC, A, B, CC, DP and their lower case equivalents. For the push and pull operations, the D register is an alias for the A and B registers, and will result in two selection bits set in the postbyte. .H 4 "indexed" The indexed mode operands are in the forms. .VL 25 5 1 .LI ", index" .LI "expr , index" .LI "accumulator , index" .LI ", index +" .LI ", index ++" .LI ", - index" .LI ", -- index" .LI "expr , PCR" .LI "[ , index ]" .LI "[ expr , index ]" .LI "[ accumulator , index ]" .LI "[ , index ++ ]" .LI "[ , -- index ]" .LI "[ expr , PCR ]" .LI "[ expr ]" .LE .P Index can be any of X, Y, S, U (or their lower case equivalents). Accumulator can be any of A, B, D (or their lower case equivalents). .P The short offset forms will only be used if the expression in the operand has a value defined at the first pass, and the value is small enough to fit. Expressions that have an as yet undefined value will use the 16 bit offset form. .H 3 "Selection Criteria Keywords" .VL 25 5 .LI DIRECT The instruction can use the direct addressing mode. The expression must have a value between 0 and 255 that is defined when the instruction is processed in the input pass. .LI EXTENDED The instruction can use the extended addressing mode. .LE .H 3 "Apostrophes" The apostrophes in the syntax field are a notation used for the parser generator and are not put in the assembler source statement. .H 2 "Notes" .H 3 "Reserved Symbols" .H 4 "Machine Dependent Reserved Symbols" A B CC D DP PC PCR S U X Y a b cc d dp pc pcr s u x y .H 4 "Standard Reserved Symbols" AND DEFINED EQ GE GT HIGH LE LOW LT MOD NE NOT OR SHL SHR XOR and defined eq ge gt high le low lt mod ne not or shl shr xor .TC 1 1 7
