Data Sheet

V 0.2, 2002-01
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
compare channel.
Generation of a three-phase PWM supported (six outputs, individual signals for
highside and lowside switches)
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.
