• A mask operation

For A mask, the above operation is modified as follows:

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

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

Special properties of compare match flag disappear and compare match flags of buffer

registers are set to all set values of buffer registers.

Figure 12.92 shows an example when setting the duty setting register to TGR3B, buffer
