Section 8 Data Transfer Controller (DTC)
Section 8 Data Transfer Controller (DTC)
The H8S/2268 Group includes a data transfer controller (DTC), while the H8S/2264 Group does
not. 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.
8.1
Features
• 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)
• The 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
