status of the other H1#2 and H2#2 to H1#12 and H2#12 process is not included for status transition,
but can be included by the AISCT bit of the MDPTRR register.
•Overall indication processing
The overall status of the pointer changes depending on the status transition caused by the pointer
processing of H1#1 and H2#1 and on the status transition of each pointer caused by the concatenation
indication processing of H1#2 and H2#2 to H1#12 and H2#12.
