Capture/Compare Unit 6 (CAPCOM6)
A rich set of status bits, synchronized updating of parameter values via shadow
registers, and flexible generation of interrupt request signals provide means for efficient
software-control.
Timer 12 Block Features
• Three capture/compare channels, each channel can be used either as capture or as
compare channel
• Generation of a three-phase PWM supported (six outputs, individual signals for
highside and lowside switches)
• 16-bit resolution, maximum count frequency = peripheral clock
• Dead-time control for each channel to avoid short-circuits in the power stage
• Concurrent update of the required T12/T13 registers
• Center-aligned and edge-aligned PWM can be generated
• Single-shot mode supported
• Many interrupt request sources
• Hysteresis-like control mode
Timer 13 Block Features
• One independent compare channel with one output
• 16-bit resolution, maximum count frequency = peripheral 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
• Hall-Effect noise filter
• 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
