Section 9 16-Bit Free-Running Timer (FRT)
9.6 Interrupt Sources
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 9.2 lists the sources and priorities of these interrupts.
