INC DPTR
Function:
Increment data pointer
Description: Increment the 16-bit data pointer by 1. A 16-bit increment (modulo 2 16)
is performed; 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.
