Section 8 Data Transfer Controller (DTC)
8.3
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. Table 8.1 shows the relationship
between the activation source and DTCER clearing. The activation source flag, in the case of
RXI0, for example, is the RDRF flag in SCI_0.
Since there are a number of DTC activation sources, transferring the last byte (or word) does not
clear the flag of its activation source. Take appropriate steps at each interrupt processing.
When an interrupt has been designated a DTC activation source, the 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 8.1
Figure 8.2 shows a block diagram of activation source control. For details, see section 5, Interrupt
Controller.
