(4) | Expression and operator |
Expression represents constants, register name, SFR name and symbols and those connected with operators.
An expression comes in two types: an address expression and a watch-expression. The expression that requires the address of a symbol is referred to as an address expression, and the one that requires the value of a symbol is referred to as a watch-expression.
(a) | An address expression and operators |
With an address expression, the address of a symbol is used to perform operations. Only when a CPU register name is written, the value of the symbol is used to perform operations.
The basic input formats of address expressions are as follows:
Table 2.26 | Basic Input Format of Address Expressions |
|
|
|
|
Name of a C language variableNote 1,2
|
Address of a C language variable
|
|
Expression [ExpressionNote 3]
|
Address of an array
|
|
Expression.Member name
|
Address of a structure/union/class member
|
|
Expression->Member name
|
Address of a structure/union/class member that is pointed to
|
|
Name of a CPU register
|
Value of the CPU register
|
|
Name of a SFR
|
Address of the SFR
|
|
Label nameNote 4, EQU symbol nameNote 4 and [immediate value]
|
Address of a label, a value of an EQU symbol, and an immediate address
|
|
Integer constant
|
Address
|
Note 1. | It represents C language (C89/C99) variables. |
Note 2. | If the register is assigned the value of a C variable, an error results. |
Note 3. | The expression that is input as an index to an array is parsed as a watch-expression. |
Note 4. | If the label name or EQU symbol name includes a "$", be sure to enclose the name in "{ }" (e.g. {$Label}).
When you specify the CPU register name "I", add ":REG" (e.g. I:REG) to distinguish it from the keyword "I" that indicates an imaginary number. |
From "2.18.2 Symbol name completion function", the following expressions with operator can be constructed.

Note | Variables and functions can be combined by an operator only with variables, functions and integer constants.
Example: C variable name + SFR name |
(b) | Watch-expression and operator |
With watch-expression, the value of a symbol is used to perform operations. Only when the value does not exist, the address of the symbol is used to perform operations (e.g. main( ) + 1).
The basic input formats of watch-expressions are as follows:
Table 2.28 | Basic Input Format of Watch-expressions |
|
|
|
|
Name of a C language variableNote 1
|
Address of a C language variable
|
|

Note 1. | It represents C language (C89/C99) variables. |
Note 2. | If the label name or EQU symbol name includes a "$", be sure to enclose the name in "{ }" (e.g. {$Label}).
Any imaginary number must be multiplied by an uppercase "I" (e.g. 1.0 + 2.0*I). When you specify the CPU register name "I", add ":REG" (e.g. I:REG) to distinguish it from the keyword "I" that indicates an imaginary number. |
From "Table 2.28 Basic Input Format of Watch-expressions", the following watch-expressions with operator can be constructed. For the operators listed in the table below, the expression is parsed according to C language specifications.
