Preliminary
3.7
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.
Figure 6
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).
Data Sheet
The timer registers (T12, T13) are not directly accessible.
The period and offset registers are loading a value into the timer registers.
