For example, an assembler might support the mnemonic “CLC” (clear carry), which is interpreted the same as the instruction “clrb $03.0” (clear bit 0 in the STATUS register). Some of the commonly supported equivalent assembler mnemon- ics are described in Table 16-2. Table 16-2. Equivalent Assembler Mnemonics Syntax Description Equivalent Cycles CLC Clear Carry bit CLRB $03.0 1 CLZ Clear Zero bit CLRB $03.2 1 JMP W Jump Indirect W MOV $02,W 4 or 3 (note 1) JMP PC+W Jump Indirect W Relative ADD $02,W 4 or 3 (note 1) MODE imm4 Move Immediate to MODE Register MOV M,#lit 1 NOT W Complement W XOR W,#$FF 1 SC Skip if Carry bit Set SB $03.0 1 or 2 (note 2) SKIP Skip Next Instruction SNB $02.0 or SB $02.0 4 or 2 (note 3) Note 1: The JMP W or JMP PC+W instruction takes 4 cycles in the “compatible” clocking mode or 3 cycles in the “turbo” clocking mode. Note 2: The SC instruction takes 1 cycle if the tested condition is false or 2 cycles if the tested condition is true. Note 3: The assembler converts the SKIP instruction into a SNB or SB instruction that tests the least significant bit of the program counter, choosing SNB or SB so that the tested condition is always true. The instruction takes 4 cycles in the “compatible” clocking mode or 2 cycles in the “turbo” clocking mode. |
