DPTR
Increment data pointer
Increment the 16-bit data pointer by 1. A 16-bit increment (modulo 2
an overflow of the low-order byte of the data pointer (DPL) from 0FF H to 00 H will
increment the high-order byte (DPH). No flags are affected.
This is the only 16-bit register which can be incremented.
Registers DPH and DPL contain 12 H and 0FE H , respectively. The instruction

will change DPH and DPL to 13 H and 01 H .
