INC DPTR
Function:
Increment data pointer
Description:
Increments the 16–bit data pointer by one. A 16–bit increment (modulo 2
of the data pointer (DPL) from 0FFh to 00h increments the high byte of the data pointer (DPH) by one. An overflow
of the high byte (DPH) does not increment the high word of the extended data pointer (DPX = DR56).
Example :
Registers DPH and DPL contain 12h and 0FEh, respectively. After the instruction sequence:
DPH and DPL contain 13h and 01h, respectively.
