ANDIAND Immediate with Control RegisterANDIOperation:Assembler Syntax:#xx. D .... DAND(I) #xx,Dwhere • denotes the logical AND operatorDescription: Logically AND the 8-bit immediate operand (#xx) with the contents of thedestination control register D and store the result in the destination control register. Thecondition codes are affected only when the condition code register (CCR) is specified asthe destination operand.Restrictions: The ANDI #xx,MR instruction cannot be used immediately before anENDDO or RTI instruction and cannot be one of the last three instructions in a DO loop(at LA-2, LA-1, or LA).The ANDI #xx,CCR instruction cannot be used immediately before an RTI instruction.Example:AND #$FE,CCR;clear carry bit C in condo code registerBefore ExecutionCCR~I _______ $_3_1 ______ ~After ExecutionCCR~I _______ $_30 ______ ~Explanation of Example: Prior to execution, the 8-bit condition code register (CCR)contains the value $31. The AND #$FE,CCR instruction logically ANDs the immediate 8-bit value $FE with the contents of the condition code register and stores the result in thecondition code register.-
