5.6.5
The DTC can be activated by an interrupt. In this case, the following options are available:
For details on interrupt requests that can be used to activate the DTC, see section 7, Data Transfer
Controller (DTC).
Figure 5.8 shows a block diagram of the DTC and interrupt controller.
Selection of Interrupt Source: Interrupt factors are selected as DTC activation source or CPU
interrupt source by the DTCE bit of DTCERA to DTCERE of DTC.
By specifying the DISEL bit of the DTC’s MRB, it is possible to clear the DTCE bit to 0 after
DTC data transfer, and request a CPU interrupt.
If DTC carries out the designate number of data transfers and the transfer counter reads 0, after
DTC data transfer, the DTCE bit is also cleared to 0, and an interrupt is requested to the CPU.
