DPTR, #data16
Load data pointer with a 16-bit constant
The data pointer is loaded with the 16-bit constant indicated. The 16 bit constant is
loaded into the second and third bytes of the instruction. The second byte (DPH) is
the high-order byte, while the third byte (DPL) holds the low-order byte. No flags are
affected.
This is the only instruction which moves 16 bits of data at once.
The instruction
MOV
will load the value 1234 H into the data pointer: DPH will hold 12 H and DPL will hold
34 H .
