Logical sum (immediate).
[Syntax]
The following can be specified for imm:
- | Absolute expression having a value of up to 32 bits |
- | Either of the above expressions with HIGHW, LOWW, or HIGHW1 applied |
[Function]
ORs the value of the absolute expression, relative expression, or expression with HIGHW, LOWW, or HIGHW1 applied specified by the first operand with the value of the register specified by the second operand, and stores the result in the register specified by the third operand.
[Description]
- | If the following is specified for imm, the assembler generates one ori machine instructionNote 1. |
(a) | Absolute expression having a value in the range of 0 to 65,535 |
ori imm16, reg1, reg2
|
ori imm16, reg1, reg2
|
(b) | Relative expression having !label or %labelNote 2 |
ori !label, reg1, reg2
|
ori !label, reg1, reg2
|
ori %label, reg1, reg2
|
ori %label, reg1, reg2
|
(c) | Expression with HIGHW, LOWW, or HIGHW1 |
ori imm16, reg1, reg2
|
ori imm16, reg1, reg2
|
Note 1. | The ori machine instruction takes an immediate value of 0 to 65,535 (0 to 0xFFFF) as the first operand. |
Note 2. | !label and %label are treated as 16-bit value (zero-extended). |
- | If the following is specified for imm, the assembler executes instruction expansion to generate multiple machine instructions. |
(a) | Absolute expression having a value in the range of -16 to -1 |
