Notes on Compare Match Flags in Complementary PWM Mode

In complementary PWM mode, buffer register compare-match flags can be set only for compare

with three counters (TCNT3, TCNT4, and TCNTS).

Note that when the buffer register set value is dead time (Td), 2Td, TGR3A – Td, or

TGR3A – 2Td, the buffer register compare-match flag may not be set.

Figure 12.91 gives a description when TGR3B is the specified duty setting register, TGR3D the

buffer register with TGR3A – Td as the buffer register set value.
