4.6
The dual data pointer accelerates the moving of block data. The standard DPTR is a 16-bit register
that is used to address external memory or peripherals. In the SM59D03G2, the standard data
pointer is called DPTR，the second data pointer is called DPTR1. The data pointer select bit
chooses the active pointer. The data pointer select bit is located in the LSB of DPS register
(DPS.0).
The user switches between pointers by toggling the LSB of DPS register. All DPTR-related
instructions use the currently selected DPTR for any activity.
