XMEGA D4 has four Timer/Counters, three Timer/Counter 0 and one Timer/Counter 1. The dif-
ference between them is that Timer/Counter 0 has four Compare/Capture channels, while
Timer/Counter 1 has two Compare/Capture channels.
The Timer/Counters (T/C) are 16-bit and can count any clock, event or external input in the
microcontroller. A programmable prescaler is available to get a useful T/C resolution. Updates of
Timer and Compare registers are double buffered to ensure glitch free operation. Single slope
PWM, dual slope PWM and frequency generation waveforms can be generated using the Com-
pare Channels.
Through the Event System, any input pin or event in the microcontroller can be used to trigger
input capture, hence no dedicated pins are required for this. The input capture has a noise can-
celler to avoid incorrect capture of the T/C, and can be used to do frequency and pulse width
measurements.
A wide range of interrupt or event sources are available, including T/C Overflow, Compare
match and Capture for each Compare/Capture channel in the T/C.
PORTC has one Timer/Counter 0 and one Timer/Counter1. PORTD and PORTE each have one
Timer/Conter0. Notation of these are TCC0 (Time/Counter C0), TCC1, TCD0 and TCE0,
respectively.
