Interrupt Sources

Interrupt Sources and Priorities
There are three kinds of interrupt source; TGR input capture/compare match, TCNT overflow, and TCNT underflow.
Each interrupt source has its own enable/disable bit, allowing the generation of interrupt request signals to be enabled or
disabled individually.
When an interrupt source is generated, if the corresponding enable/disable bit in TIER is set to 1, an interrupt is
requested.
Relative channel priorities can be changed by the interrupt controller; however the priority within a channel is fixed. For
details, refer to
section 14, Interrupt Controller (ICUb)
lists the MTU interrupt sources.
Table 19.62
MTU Interrupt Sources
Note:
This table shows the initial state immediately after a reset. The relative channel priorities can be changed by the interrupt
controller.
Note 1. Underflow is available only in complementary PWM mode.
