When the DTC is activated, one control data is selected according to the data read from the vector table which
has been assigned to each activation source, and the selected control data is read from the DTC control data
area.
to each activation source and one value from 00000000b to 00010111b (control data numbers in
Table 13.7) is
stored in each area to select one of the 24 control data sets.
Figures
13.3 to
13.7 show the DTC Internal Operation Flowchart.
Notes:
1. The TSCU DTC activation source must be used only for DTC transfers with interrupts set to be disabled.
Note that only this source can be used for DTC transfers during wait mode.
2. The measurement complete source must be used while DTC transfers are disabled (the DTCEN61 bit in the
DTCEN6 register is 0).
