The advanced waveform extension (AWeX) provides extra functions to the timer/counter in
waveform generation (WG) modes. It is primarily intended for use with different types of motor
control and other power control applications. It enables low- and high side output with dead-time
insertion and fault protection for disabling and shutting down external drivers. It can also gener-
ate a synchronized bit pattern across the port pins.

Four dead-time insertion (DTI) units
Pattern generation unit creating synchronised bit pattern across the port pins
Event controlled fault protection for instant and predictable fault triggering
– 8-bit resolution
– Separate high and low side dead-time setting
– Double buffered dead time
– Optionally halts timer during dead-time insertion
– Double buffered pattern generation
– Optional distribution of one compare channel output across the port pins
