Figure 8.4 shows the correspondence between DTC vector addresses and register information
allocation. For each DTC activating source there are 2 bytes in the DTC vector table, which
contain the register information start address.
Table 8.1 shows the correspondence between activating sources and vector addresses. When
activating with software, the vector address is calculated as H'0400 + DTVEC[7:0].
Through DTC activation, a register information start address is read from the vector table, then
register information placed in memory space is read from that register information start address.
Always designate register information start addresses in multiples of four.
