Mnemonic: DPL1
Address: 84h
This is the low byte of the new additional 16-bit data pointer that has been added to the W77LE58.
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 DPH1 in place of DPL and DPH. If they are not
required they can be used as conventional register locations by the user.
