Data Pointer
The VRS550 and VRS560 have one 16-bit data
pointer. The DPTR is accessed through two SFR
addresses: DPL located at address 82h and DPH
located at address 83h.
Data Memory
The VRS550 and the VRS560 have a total of: 256 bytes
of RAM configured like the internal memory structure of
a standard 8052.

Lower 128 bytes (00h to 7Fh, Bank 0 & Bank 1)
The lower 128 bytes of data memory (from 00h to 7Fh)
can be summarized in the following points:
Address range 00h to 7Fh can be accessed in
direct and indirect addressing modes.
Address range 00h to 1Fh includes R0-R7
registers area.
Address range 20h to 2Fh is bit addressable.
Address range 30h to 7Fh is not bit addressable
and can be used as general-purpose storage.
Upper 128 bytes (80h to FFh, Bank 2 & Bank 3)
The upper 128 bytes of the data memory ranging from
80h to FFh can be accessed using indirect addressing
or by using the bank mapping in direct addressing
mode.
