Capture/Compare Unit (CCU6)
The CCU6 provides two independent timers (T12, T13), which can be used for PWM
generation, especially for AC-motor control. Additionally, special control modes for block
commutation and multi-phase machines are supported.
Timer 12 Features
• Three capture/compare channels, each channel can be used either as capture or as
• Generation of a three-phase PWM supported (six outputs, individual signals for
• 16 bit resolution, maximum count frequency = system clock
• Dead-time control for each channel to avoid short-circuits in the power stage
• Concurrent update of the required T12/13 registers
• Center-aligned and edge-aligned PWM can be generated
• Single-shot mode supported
• Many interrupt request sources
• Hysteresis-like control mode
Timer 13 Features
• One independent compare channel with one output
• 16 bit resolution, maximum count frequency = system clock
• Can be synchronized to T12
• Interrupt generation at period-match and compare-match
• Single-shot mode supported
Additional Features
• Block commutation for Brushless DC-drives implemented
• 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
• Capture/compare unit can be powerdown in normal, idle and slow-down modes
The timer T12 can work in capture and/or compare mode for its three channels. The
modes can also be combined. 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.
