(5) Data differential mode (with memory pointer): DTADIF-P
Operation
This is the data differential mode in (4) with a memory pointer (MEM.PTR) appended. The
appended MEM.PTR 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 MEM.PTR and MSC
Note
. The
value of MEM.PTR is not updated after the data has been transferred.

Application example:
Same as (4)
(6) CPU monitoring mode0: SFLF0
Operation (a) Checks the internal operation of the CPU.
(b) When the blocks are operating normally, the value given by subtracting 10 from the initial
value is transferred to the SFR specified by the SFR pointer (SFR.PTR).
Application example:
Used for self checking of the CPU during normal operation.
(7) CPU monitoring mode1: SELF1
Operation (a) Checks the internal operation of the CPU.
(b) When the blocks are operating normally, the value given by subtracting 8 from the initial
value is transferred to the SFR specified by the SFR pointer (SFR.PTR).
Application example:
Used for self checking of the CPU during normal operation.
