DMA
A programmable DMA channel may be assigned by CPU firmware to service each
timer/counter module TIM0 and TIM1 for fast and direct single transfers.
Three-phase induction motor controller (IMC)
The STR91xFA provides an integrated controller for variable speed motor control
applications.
Six PWM outputs are generated on high current drive pins P6.0 to P6.5 for controlling a
three-phase AC induction motor drive circuit assembly. Rotor speed feedback is provided by
capturing a tachometer input signal on pin P6.6, and an asynchronous hardware emergency
stop input is available on pin P6.7 to stop the motor immediately if needed, independently of
firmware.
16-bit free running timer/counter
Internal timer/counter clock source from a programmable 8-bit prescale of the CCU
PCLK clock output
Optional external timer/counter clock source from pin P2.4 shared by TIM0/TIM1, and
pin P2.5 shared by TIM2/TIM3. Frequency of these external clocks must be at least 4
times less the frequency of the internal CCU PCLK clock output.
Two dedicated 16-bit Input Capture registers for measuring up to two input signals.
Input Capture has programmable selection of input signal edge detection
Two dedicated 16-bit Output Compare registers for generation up to two output signals
PWM output generation with 16-bit resolution of both pulse width and frequency
One pulse generation in response to an external event
A dedicated interrupt to the CPU with five interrupt flags
The OCF1 flag (Output Compare 1) from the timer can be configured to trigger an ADC
