10.8 A/D Conversion Trigger Function

This section describes the operation of the A/D conversion triggers output in the PWM mode, triangular
wave PWM mode, high-accuracy T-PWM mode, and PWM mode with dead time. In these modes, the
TRnCCR4 and TRnCCR5 registers are used as match interrupts and for the A/D conversion trigger
function, with no influence on timer outputs in terms of the compare operation. For the A/D conversion
triggers that can be output in each mode, refer to 10.4.3 (3) A/D conversion triggers, peak inter-
rupts, and valley interrupts in each mode.

The above figure shows the A/D conversion trigger controller. As shown in this figure, it is possible to
select and perform OR output of compare match interrupts (INTTRnCC5, INTTRnCC4) and peak
interrupts (INTTRnCD), valley interrupts (INTTRnOD) interrupt signals, sub-counter peak timing, and
sub-counter valley timing.
In the case of timer R, there are two identical A/D conversion trigger controllers, and each one can be
controlled independently.
