(5) Data differential mode (with memory pointer): DTADIF-P
• Operation
This is the data differential mode in (4) above with memory pointer (MEMP). By appending MEMP,
the buffer area in which the differential data is to be stored can be set freely on the memory space.
Remarks 1.
2.
The differential calculation can be carried out only with 16-bit SFRs.
The buffer is specified by the result of operation by MEMP and MSC^Note. MEMP is
not updated after the data has been transferred.
Note MEMP – (MSC × 2) + 2
