Section 9 Data Transfer Controller (DTC)
This LSI includes a data transfer controller (DTC). The DTC can be activated by an interrupt or
software, to transfer data.
Figure 9.1 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 the on-chip RAM (1 kbyte), enabling 32-bit/1-state reading and writing of
the DTC register information.
