(5) Data differential mode (with memory pointer): DTADIF-P
Operation
This is the data differential mode in (4) with a memory pointer (MEMP) appended. The appended
MEMP can set a buffer area to which the differential data is to be stored on the memory space
freely.
Remarks 1.
The differential calculation can be performed only an SFR of 16-bit configuration.
2.
The buffer is specified by the result of an operation between MEMP and MSC
Note
. The value
of MEMP is not updated after the data has been transferred.
Note
MEMP – (MSC
