The Capture/Compare Unit 6 (CCU6) provides two independent timers (T12, T13), which
can be used for Pulse Width Modulation (PWM) generation, especially for AC-motor
control. The CCU6 also supports special control modes for block commutation and
multi-phase machines.
The timer T12 can function in capture and/or compare mode for its three channels. The
timer T13 can work in compare mode only.
The multi-channel control unit generates output patterns, which can be modulated by
T12 and/or T13. The modulation sources can be selected and combined for the signal
modulation.
Timer T12 Features:
• Three capture/compare channels, each channel can be used either as a capture or as
• Supports generation of a three-phase PWM (six outputs, individual signals for
• 16-bit resolution, maximum count frequency = peripheral clock frequency
• Dead-time control for each channel to avoid short-circuits in the power stage
• Concurrent update of the required T12/13 registers
• Generation of center-aligned and edge-aligned PWM
• Supports single-shot mode
• Supports many interrupt request sources
• Hysteresis-like control mode
Timer T13 Features:
• One independent compare channel with one output
• 16-bit resolution, maximum count frequency = peripheral clock frequency
• Can be synchronized to T12
• Interrupt generation at period-match and compare-match
• Supports single-shot mode
Additional Features:
• Implements block commutation for Brushless DC-drives
• Position detection via Hall-sensor pattern
• Automatic rotational speed measurement for block commutation
• Integrated error handling
• Fast emergency stop without CPU load via external signal (CTRAP)
• Control modes for multi-channel AC-drives
• Output levels can be selected and adapted to the power stage
