Internal signals. See Figure 15.1. The examples of PWM output change are - Default value of the IDB0 and IDB1 registers: DU0=0, DUB0=1, DU1=1, DUB1=1 They are changed to DU0=1, DUB0=0, DU1=1, DUB1=1 by the timer B2 interrupt. The above applies to INVC0 = 01XX110X2 and INVC1 = 010XXX002 (X varies depending on each system.)
