Dual data pointers
11.2
11.2.1
58/300
Data pointer mode register, DPTM (86h)
The two “background” data pointers, DPTR0 and DPTR1, can be configured to
automatically increment, decrement, or stay the same after a MOVX instruction accesses
the DPTR register. Only the currently selected pointer will be affected by the increment or
decrement. This feature is controlled by the DPTM register defined in
The automatic increment or decrement function is effective only for the MOVX instruction,
and not MOVC or any other instruction that uses the DTPR register.
Firmware example
The 8051 assembly code illustrated in
from one XDATA address region to another XDATA address region. Auto-address
incrementing and auto-pointer toggling will be used.
