Only Timer/Counter 0 has the split mode feature that split it into two 8-bit Timer/Counters with four compare channels
each.
Some timer/counters have extensions to enable more specialized waveform and frequency generation. The advanced
waveform extension (AWeX) is intended for motor control and other power control applications. It enables low- and high-
side output with dead-time insertion, as well as fault protection for disabling and shutting down external drivers. It can
also generate a synchronized bit pattern across the port pins.
The advanced waveform extension can be enabled to provide extra and more advanced features for the Timer/Counter.
The high-resolution (hi-res) extension can be used to increase the waveform output resolution by four or eight times by
Figure 15-1. Overview of a Timer/Counter and closely related peripherals.
PORTC has one Timer/Counter 0 and one Timer/Counter1. PORTD, PORTE and PORTF each has one Timer/Counter
0. Notation of these are TCC0 (Time/Counter C0), TCC1, TCD0, TCE0, and TCF0, respectively.
