Built-in Assembly FunctionsThe TASKING assembler has several built-in functions to support data conversion, string comparison,and math computations. You can use functions as terms in any expression.Syntax of an assembly function@function_name([argument[,argument]...])Functions start with the '@' character and have zero or more arguments, and are always followed byopening and closing parentheses. White space (a blank or tab) is not allowed between the function nameand the opening parenthesis and between the (comma-separated) arguments.The names of assembly functions are case insensitive.Overview of assembly functionsFunction@ALUPCREL(expr,group[,check])@ARG('symbol' | expr)@BIGENDIAN()@CNT()@CPU('architecture')@DEFINED('symbol' | symbol)@LSB(expr)@LSH(expr)DescriptionPC-relative ADD/SUB with operand splitTest whether macro argument is presentTest if assembler generates code for big-endian modeReturn number of macro argumentsTest if current CPU matches architectureTest whether symbol existsLeast significant byte of the expressionLeast significant half word of the absolute expression91
