Interrupt Sources and Priorities

This module has three kinds of interrupt sources; 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 7, Interrupt Controller.
Table 10.55 lists the interrupt sources of this module.
