Dual Data Pointer: The Dual Data Pointer accelerates the block moves of data. The standard DPTR is a
16-bit register that is used to address external memory. In the 80515 core, 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 at the LSB of the
(DPS.0). DPTR is selected when DPS.0 = 0 and DPTR1 is selected when DPS.0 = 1.
The user switches between pointers by toggling the LSB of the
instructions use the currently selected DPTR for any activity.
Rev. 1.4
The second data pointer may not be supported by certain compilers.
