Operation Assembler Syntax

#u16 ⏐ DR.L → DR.L

#u16 ⏐ DR.H → DR.H

OR #u16,DR.H {0 ≤ u16 < 2

}

OR #u16,DR.L

Performs a bitwise inclusive OR of an immediate value with the LP of a data or address register (DR). It

then stores the result in the LP of the destination data or address register (DR). The other register bits are

not affected. This instruction is assembler-mapped to BMSET #u16,DR.L with the immediate value.

OR #u16,DR.H

Performs a bitwise inclusive OR of an immediate value with the HP of a data or address register (DR). It

then stores the result in the HP of the destination data or address register (DR). The other register bits are

not affected. This instruction is assembler-mapped to BMSET #u16,DR.H with the immediate value.

Ln L Clears the Ln bit in the destination registers.
