The AC induction motor control utilizes the PWM block set in the complementary PWM mode, permitting generation of control signals for all switches of the power stage with inserted dead time. The PWM block generates three sinewave outputs mutually shifted by 120 degrees. The Analog-to-Digital Converter (ADC) consists of a digital control module and two analog Sample and Hold (S/H) circuits. ADC features: • 12-bit resolution • Maximum ADC clock frequency is 5MHz with 200ns period • Single conversion time of 8.5 ADC clock cycles (8.5 x 200ns = 1.7µs) • Additional conversion time of 6 ADC clock cycles (6 x 200ns = 1.2µs) • Eight conversions in 26.5 ADC clock cycles (26.5 x 200ns = 5.3µs) using simultaneous mode • ADC can be synchronized to the PWM via the sync signal • Simultaneous or sequential sampling • Internal multiplexer to select two of eight inputs • Ability to sequentially scan and store up to eight measurements • Ability to simultaneously sample and hold two inputs • Optional interrupts at end of scan, if an out-of-range limit is exceeded, or at zero crossing • Optional sample correction by subtracting a preprogrammed offset value • Signed or unsigned result • Single-ended or differential inputs

The application utilizes the ADC block in simultaneous mode and sequential scan. It is synchronized with PWM pulses. This configuration allows the simultaneous conversion within the required time of required analog values, of all phase currents, voltage and temperature. The Quad Timer is an extremely flexible module, providing all required services relating to time events. It has the following features: • Each timer module consists of four 16-bit counters / timers • Counts up / down • Counters are cascadable • Programmable count modulo • Maximum count rate equals peripheral clock/2 when counting external events • Maximum count rate equals peripheral clock when using internal clocks • Counts once or repeatedly • Counters are preloadable • Counters can share available input pins• Each counter has a separate prescaler • Each counter has capture and compare capability
