Overview
Counter A and Counter B are 8-bits counters and can be combined to form a 16-bit counter. Counter C and
Counter D exhibit the same feature.
The counters can also be used to generate two PWM outputs on PB[0] and PB[1]. In PWM mode one can generate
PWM functions with 8, 10, 12, 14 or 16 bits wide counters.
The counters A and B can be captured by events on an internal or an external signal. The capture can be
performed on both 8-bit counters running individually on two different clock sources or on both counters chained to
form a 16-bit counter. In any case, the same capture signal is used for both counters.
When the counters A and B are not chained, they can be used in several configurations: A and B as counters, A
and B as captured counters, A as PWM and B as counter, A as PWM and B as captured counter.
When the counters C and D are not chained, they can be used either both as counters or counter C as PWM and
counter D as counter.
