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.
Table 15.5 shows the DTC Activation Sources and DTC Vector Addresses. A one-byte vector table area is
assigned to each activation source and one value from 00000000b to 00010111b (control data numbers in Table
15.4) is stored in each area to select one of the 24 control data sets.
Figures 15.3 to 15.7 show the DTC Internal Operation Flowchart.
