16.1
Some assemblers support additional instruction mne-
monics that are special cases of existing instructions or
alternative mnemonics for standard ones. 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.

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.
