counter value matches the TOP value. The counter is then cleared at the following timer clock
cycle. The TCNT4 value is in the timing diagram shown as a histogram for illustrating the single-
slope operation. The timing diagram includes Output Compare pins OC4A and OC4A, and the
corresponding Output Compare Override Enable bits (OC4OE1..OC4OE0).
Figure 15-15. PWM6 Mode, Single-slope Operation, Timing Diagram
The general I/O port function is overridden by the Output Compare value (OC4x / OC4x) from
the Dead Time Generator if either of the COM4x1:0 bits are set. The Output Compare pins can
also be overridden by the Output Compare Override Enable bits OC4OE5..OC4OE0. 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 15-5.
