The Advanced Waveform Extension (AWEX) provides extra features to the Timer/Counter in
Waveform Generation (WG) modes. The AWEX enables easy and safe implementation of for
example, advanced motor control (AC, BLDC, SR, and Stepper) and power control applications.
Any WG output from a Timer/Counter 0 is split into a complimentary pair of outputs when any
AWEX feature is enabled. These output pairs go through a Dead-Time Insertion (DTI) unit that
enables generation of the non-inverted Low Side (LS) and inverted High Side (HS) of the WG
output with dead time insertion between LS and HS switching. The DTI output will override the
normal port value according to the port override setting. Optionally the final output can be
inverted by using the invert I/O setting for the port pin.
The Pattern Generation unit can be used to generate a synchronized bit pattern on the port it is
connected to. In addition, the waveform generator output from Compare Channel A can be dis-
tributed to, and override all port pins. When the Pattern Generator unit is enabled, the DTI unit is
bypassed.
The Fault Protection unit is connected to the Event System. This enables any event to trigger a
fault condition that will disable the AWEX output. Several event channels can be used to trigger
fault on several different conditions.
The AWEX is available for TCC0. The notation of this is AWEXC.
