Bytes:
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 DPTR, # 1234h
will load the value 1234h into the Data Pointer: DPH will hold 12h and DPL will
hold 34h.
