Expressions

Many debug commands accept numeric expressions as parameters. A numeric expression is a number or a complex expressions that contains numbers, debug objects, or operands. An expression may consist of any of the following components.

Component	Description
Bit Addresses	Bit addresses reference bit-addressable data memory.
Constants	Constants are fixed numeric values or character strings.
Line Numbers	Line numbers reference code addresses of executable programs. When you compile or assemble a program, the compiler and assembler include line number information in the generated object module.
Operators	Operators include +, -, *, and /. Operators may be used to combine subexpressions into a single expression. You may use all operators that are available in the C programming language.
Program Variables	Program variables are those variables in your target program. They are often called symbols or symbolic names.
System Variables	System variables alter or affect the way µVision3 operates.
Peripheral Variables	Peripheral (or SFR) variables allow access the simulated on-chip peripherals.
Type Specifications	Type specifications let you specify the data type of an expression or subexpression.
