Figure 12-14. PWM6 Mode, Single-slope Operation, Timing Diagram
The general I/O port function is overridden by the Output Compare value (OC1x / OC1x) from
the Dead Time Generator if either of the COM1x1:0 bits are set. The Output Compare pins can
also be overriden by the Output Compare Override Enable bits OC1OE5:OC1OE0. If an Over-
ride Enable bit is cleared, the actual value from the port register will be visible on the port pin
and, if the Override Enable bit is set, the Output Compare pin is allowed to be connected on the
port pin. The Output Compare Pin configurations are described in
Table
Table 12-5.
