• Manufacturer Part Number: h8s-2161b
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2100 Series
• Manufacturer: Renesas Electronics Corporation.

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.
