The Capture/Compare Unit CAPCOM6
The CAPCOM6 unit supports generation and control of timing sequences on up to three
16-bit capture/compare channels plus one independent 10-bit compare channel.
In compare mode the CAPCOM6 unit provides two output signals per channel which
have inverted polarity and non-overlapping pulse transitions (deadtime control). The
compare channel can generate a single PWM output signal and is further used to
modulate the capture/compare output signals.
In capture mode the contents of compare timer T12 is stored in the capture registers
upon a signal transition at pins CCx.
Compare timers T12 (16-bit) and T13 (10-bit) are free running timers which are clocked
by the prescaled system clock.

CAPCOM6 Block Diagram
For motor control applications both subunits may generate versatile multichannel PWM
signals which are basically either controlled by compare timer T12 or by a typical hall
sensor pattern at the interrupt inputs (block commutation).

The timer registers (T12, T13) are not directly accessible.
The period and offset registers are loading a value into the timer registers.
