11.6
The free-running timer can request seven interrupts: ICIA to ICID, OCIA, OCIB, and FOVI. Each
interrupt can be enabled or disabled by an enable bit in TIER. Independent signals are sent to the
interrupt controller for each interrupt. Table 11.2 lists the sources and priorities of these interrupts.
The ICIA, ICIB, OCIA, and OCIB interrupts can be used as the on-chip DTC activation sources.
