10.3
The DTC operates when activated by an interrupt or by a write to DTVECR or DTCCR by
software. An interrupt request can be directed to the CPU or DTC, as designated by the
corresponding DTCER bit. At the end of a data transfer (or the last consecutive transfer in the case
of chain transfer), the activation source or corresponding DTCER bit is cleared. The activation
source flag, in the case of RXI0, for example, is the RDRF flag of SCI_0.
When an interrupt has been designated a DTC activation source, existing CPU mask level and
interrupt controller priorities have no effect. If there is more than one activation source at the same
time, the DTC operates in accordance with the default priorities.
Table 10.1 shows a relationship between activation sources and DTCER clear conditions. Figure
10.2 shows a block diagram of activation source control. For details see section 6, Interrupt
Controller.
