5.6.2
Figure 5.9 shows a block diagram of the DTC interrupt controller.
5.6.3
The interrupt controller has three main functions in DTC control.
(1) Selection of Interrupt Source
Interrupt sources can be specified as DTC activation requests or CPU interrupt requests by means
of the DTCE bit of DTCEA to DTCEE in the DTC.
After a DTC data transfer, the DTCE bit can be cleared to 0 and an interrupt request sent to the
CPU in accordance with the specification of the DISEL bit of MRB in the DTC.
When the DTC has performed the specified number of data transfers and the transfer counter value
is zero, the DTCE bit is cleared to 0 and an interrupt request is sent to the CPU after the DTC data
transfer.
