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.
