10.5 Interrupts
Section 10 Multi-Function Timer Pulse Unit (MTU)
10.5.1 Interrupts and Priorities
There are three kinds of MTU interrupt source; TGR input capture/compare match, TCNT
overflow, and TCNT underflow. Each interrupt source has its own status flag and enable/disabled
bit, allowing the generation of interrupt request signals to be enabled or disabled individually.
When an interrupt request is generated, the corresponding status flag in TSR is set to 1. If the
corresponding enable/disable bit in TIER is set to 1 at this time, an interrupt is requested. The
interrupt request is cleared by clearing the status flag to 0.
Relative channel priorities can be changed by the interrupt controller, however the priority order
within a channel is fixed. For details, see section 6, Interrupt Controller (INTC).
Table 10.42 lists the TPU interrupt sources.
