This LSI includes a data transfer controller (DTC). The DTC can be activated by an interrupt or
software, to transfer data.
Figure 7.1 shows a block diagram of the DTC. The DTC's register information is stored in the on-
chip RAM. When the DTC is used, the RAME bit in SYSCR must be set to 1. A 32-bit bus
connects the DTC to addresses H'(FF)EC00 to H'(FF)EFFF in on-chip RAM (1 kbyte), enabling
32-bit/1-state reading and writing of the DTC register information.

Transfer is possible over any number of channels
Three transfer modes
Normal, repeat, and block transfer modes are available.
One activation source can trigger a number of data transfers (chain transfer)
Direct specification of 16-Mbyte address space is possible
Activation by software is possible
Transfer can be set in byte or word units
A CPU interrupt can be requested for the interrupt that activated the DTC
Module stop mode can be set
