(A byte is comprised of 8 bits. Starting from the lowest bit of the register, B0,each successive eight bits form a byte, so B0~B7 form byte 0, B8~B15 form byte 1, etc...)• When the operand is 16 bit, the effective range of Ns or Nd is 0~1. For 32 bit ( D instruction) operand, therange is 0~3. Beyond this range, will set the N value error flag "ERR" to 1, and do not carry out thisinstruction.X044DP.BYMVEN S : R 0 ERRNs : 2D : R 2Nd : 1• The instruction at left moves the third byte (B16~B23)within S (32 bit register composed of R1R0), to the firstbyte within D (32 bit register composed of R3R2). Otherbytes within D remain unchanged.B15S R1 R0 1 0 1 1 1 0 1 1B0Byte3 Byte2 Byte1 Byte0Ns=2────────────── X0=Nd=1────────────────────Byte3 Byte2 Byte1 Byte0D R3 R2 1 0 1 1 1 0 1 1B31B07-19
