and 4 is valid only for timer/counter 0. 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 gen-
eration. 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 syn-
chronized bit pattern across the port pins.
The advanced waveform extension can be enabled to provide extra and more advanced fea-
tures for the Timer/Counter. This are only available for Timer/Counter 0. See
Advanced Waveform Extension” on page 37
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
Figure 15-1. Overview of a Timer/Counter and closely related peripherals.
PORTC has one Timer/Counter 0 and one Timer/Counter1. PORTD and PORTE each has one
Timer/Conter0. Notation of these are TCC0 (Time/Counter C0), TCC1, TCD0 and TCE0,
respectively.
