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.
This are only available for Timer/Counter 0. See “AWeX – Advanced Waveform Extension” on page 37 for more details.
The high-resolution (hi-res) extension can be used to increase the waveform output resolution by four or eight times by
using an internal clock source running up to four times faster than the peripheral clock. See “Hi-Res – High Resolution
Extension” on page 38 for more details.
Figure 17-1. Overview of a Timer/Counter and closely related peripherals.
PORTC, PORTD and PORTE each has one Timer/Counter 0 and one Timer/Counter1. PORTF has one Timer/Counter
0. Notation of these are TCC0 (Time/Counter C0), TCC1, TCD0, TCD1, TCE0, TCE1 and TCF0, respectively.
