(A nibble is comprised by 4 bits. Starting from the lowestbit of the register, B0, each successive 4 bits form a nibble, so B0~B3 form nibble 0, B4~B7 form nibble 1,etc...)• When the operand is 16 bit, the effective range of Ns or Nd is 0~3. For 32 bit ( D instruction) operand therange is 0~7. Beyond this range, will set the N value error flag "ERR" to 1 , and do not carry out thisinstruction.X043P.NBMVEN S : R 0Ns : 2ERR• The instruction at left moves the third nibble NB2(B8~B11) within S to the first nibble NB1 (B4~B7) withinD.
