11.6 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 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.
Table 11.2 FRT Interrupt Sources
Interrupt Interrupt Source Interrupt Flag DTC Activation Priority
ICIA Input capture of ICRA ICFA Possible High
ICIB Input capture of ICRB ICFB Possible
ICIC Input capture of ICRC ICFC Not possible
ICID Input capture of ICRD ICFD Not possible
OCIA Compare match of OCRA OCFA Possible
OCIB Compare match of OCRB OCFB Possible
FOVI Overflow of FRC OVF Not possible Low
