18.3.4.2 State Selection
To support a wide range of power switches and drivers, the state selection offers the flexibility to define when
an output can be active and can be modulated, especially useful for
complementary or multi-phase PWM
signals.
The state selection is based on the signals CC6xST and CC6xST delivered by the dead-time generator (see
). Both signals are never active at the same time, but can be passive at the same time. This happens
during the dead-time of each compare channel after a change of the corresponding State Bit CC6xST.
The user can select independently for each output signal CC6xO and COUT6xO if it should be active before or
after the compare value has been reached (see register CMPSTAT). With this selection, the active (conducting)
phases of complementary power switches in a power inverter bridge leg can be positioned with respect to the
compare value (e.g. signal CC6xO can be active before, whereas COUT6xO can be active after the compare
value is reached). Like this, the output modulation, the trap logic and the output level selection can be
programmed independently for each output signal, although two output signals are referring to the same
compare channel.
