Section 9 Data Transfer Controller (DTC)
9.3
The DTC operates when activated by an interrupt or by a write to DTVECR 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 9.1 shows a relationship between activation sources and DTCER clear conditions. Figure
9.2 shows a block diagram of activation source control. For details see section 5, Interrupt
Controller.
