11.5 Interrupt Sources
TCM has five interrupt sources: TICI, TCMI, TOVMI, TUDI, and TOVI. Each interrupt source is
either enabled or disabled by the corresponding interrupt enable bit in TCMIER and independently
transferred to the interrupt controller. Since a single vector address is allocated for each type of
interrupt source from all channels, the flags must be used to discriminate between the sources.
Table 11.3 lists the interrupt sources in priority order.
