Capture/Compare Unit 6 (CCU6)
Figure 11 shows a global view of all functional blocks of two Capture/Compare Units
(CCU60 & CCU61).
Both of the CCU6 modules is further supplied by clock control, interrupt control, address
decoding, and port control logic. One DMA request can be generated by each CCU6
module.
Each 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
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 T12/13 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 = 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
• 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
