9.5.6 Interrupt Sources
Timer X has three types of interrupts and seven interrupt sources: ICIA to ICID, OCIA, OCIB,
and FOVI. Table 9.18 lists the sources of interrupt requests. Each interrupt source can be enabled
or disabled by an interrupt enable bit in TIER. Although all seven interrupts share the same vector,
they have individual interrupt flags, so software can discriminate the interrupt source.
