• Description: 16-bit Single-chip Microcontroller
• Manufacturer: Infineon Technologies Corporation

Preliminary
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 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. 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 12 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 CPU clock.
Figure 5
For motor control applications both subunits may generate versatile multichannel PWM
signals which are basically either controlled by compare timer 12 or by a typical hall
sensor pattern at the interrupt inputs (block commutation).
Note: Multichannel signal generation is provided only in devices with a full CAPCOM6.
Data Sheet
The timer registers (T12, T13) are not directly accessible.
The period and offset registers are loading a value into the timer registers.
The shaded blocks are available in the full function module only.
