Note: The DTC is not implemented in the H8S/2635 Group.
5.6.1
The DTC can be activated by an interrupt. In this case, the following options are available:
• Interrupt request to CPU
• Activation request to DTC
• Selection of a number of the above
For details of interrupt requests that can be used with to activate the DTC, see section 8, Data
Transfer Controller (DTC).
5.6.2
Figure 5-9 shows a block diagram of the DTC interrupt controller.
