• Manufacturer Part Number: h8s-2628
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 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 8.1 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.
