Assembler User GuideNumeric expressions
Numeric expressions consist of combinations of numeric constants, numeric variables, ordinary numeric literals, binary operators, and parentheses. Numeric expressions can contain register-relative or program-relative expressions if the overall expression evaluates to a value that does not include a register or the PC. Numeric expressions evaluate to 32-bit integers. You can interpret
them as unsigned numbers in the range 0 to 232-1,
or signed numbers in the range -231 to
231-1. However, the assembler makes no
distinction between -
a SETA 256*256 ; 256*256 is a numeric expression
MOV r1,#(a*22) ; (a*22) is a numeric expression
