Interrupts
The free-running timer can request seven interrupts (three types): input capture A to D (ICIA,
ICIB, ICIC, ICID), output compare A and B (OCIA and OCIB), and overflow (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 8.4 lists information about these interrupts.
