W925E/C625
8-bit CID Microcontroller
SP:
Revision : A6
-14-
Release Date : 2002/7/2
The Stack Pointer stores the scratchpad RAM address where the stack begins. In other
words, it always points to the top of the stack.

Mnemonic: DPL1
This is the low byte of the new additional 16-bit data pointer that has been added to the
W925E/C625. The user can switch between DPL, DPH and DPL1, DPH1 simply by
setting register DPS.0 = 1. The instructions that use DPTR will now access DPL1 and
DPH1 in place of DPL and DPH. If they are not required they can be used as
conventional register locations by the user.

This is the high byte of the new additional 16-bit data pointer that has been added to the
W925E/C625. The user can switch between DPL, DPH and DPL1, DPH1 simply by
setting register DPS = 1. The instructions that use DPTR will now access DPL1 and

DPS.0
Mnemonic: DPS
Address: 86h
DPS.0: This bit is used to select either the DPL,DPH pair or the DPL1,DPH1 pair as the active
Data Pointer. When set to 1, DPL1,DPH1 will be selected, otherwise DPL,DPH will be
selected.
DPS.1-7:These bits are reserved, but will read 0.
