Note: This table shows the initial state immediately after a reset. The relative channel priority can
be changed by the interrupt controller.
Input Capture/Compare Match Interrupt: An interrupt is requested if the TGIE bit in TIER is
set to 1 when the TGF flag in TSR is set to 1 by the occurrence of a TGR input capture/compare
match on a particular channel. The interrupt request is cleared by clearing the TGF flag to 0. The
MTU has 16 input capture/compare match interrupts, four each for channels 0, 3, and 4, and two
each for channels 1 and 2.
