Table 8.2
8.3.2
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. An interrupt becomes a DTC activation source when the corresponding bit is set to 1, and a
CPU interrupt source when the bit is cleared to 0.
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 8.3 shows activation source and
DTCER clearance. The activation source flag, in the case of RXI0, for example, is the RDRF flag
of SCI0.
