• Manufacturer Part Number: h8s-2646
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

8.1
The H8S/2646 Group includes a data transfer controller (DTC). The DTC can be activated by an
interrupt or software, to transfer data.
8.1.1
• Transfer possible over any number of channels
• Wide range of transfer modes
• Direct specification of 16-Mbyte address space possible
• Transfer can be set in byte or word units
• A CPU interrupt can be requested for the interrupt that activated the DTC
• Activation by software is possible
• Module stop mode can be set
 Transfer information is stored in memory
 One activation source can trigger a number of data transfers (chain transfer)
 Normal, repeat, and block transfer modes available
 Incrementing, decrementing, and fixing of source and destination addresses can be selected
 24-bit transfer source and destination addresses can be specified
 An interrupt request can be issued to the CPU after one data transfer ends
 An interrupt request can be issued to the CPU after the specified data transfers have
 The initial setting enables DTC registers to be accessed. DTC operation is halted by setting
completely ended
module stop mode.
