Timer 3 consists of an 8-bit up-counter with two compare registers and one capture register. The
timer can be used as event counter, timer and signal generator. Its output can be programmed
as modulator and demodulator for the serial interface. The two compare registers enable various
modes of signal generation, modulation and demodulation. The counter can be driven by inter-
nal and external clock sources. For external clock sources, it has a programmable edge-
sensitive input which can be used as counter input, capture signal input or trigger input. This
timer input is synchronized with SYSCL. Therefore, in the power-down mode SLEEP (CPU core
capture register while it is running. In capture mode, the counter value can be captured by a pro-
grammable capture event from the Timer 3 input or Timer 2 output.
