Section 8 Data Transfer Controller (DTC)
8.3.3
Figure 8-4 shows the correspondence between DTC vector addresses and register information.
Table 8-4 shows the correspondence between activation and vector addresses. When the DTC is
activated by software, the vector address is obtained from: H'0400 + (DTVECR[6:0] << 1) (where
<< 1 indicates a 1-bit left shift). For example, if DTVECR is H'10, the vector address is H'0420.
The DTC reads the start address of the register information from the vector address set for each
activation source, and then reads the register information from that start address. The register
information can be placed at predetermined addresses in the on-chip RAM. The start address of
the register information should be an integral multiple of four.
The configuration of the vector address is the same in both normal * and advanced modes, a 2-byte
unit being used in both cases. These two bytes specify the lower bits of the address in the on-chip
RAM.
Note: * Not available in the chip.
