Stellaris® LM3S3749 Microcontroller
⢠PWM output enable of each PWM signal
⢠Optional output inversion of each PWM signal (polarity control)
⢠Optional fault handling for each PWM signal
⢠Synchronization of timers in the PWM generator blocks
⢠Extended PWM synchronization of timer/comparator updates across the PWM generator
blocks
⢠Interrupt status summary of the PWM generator blocks
⢠Extended PWM fault handling, with multiple fault signals, programmable polarities, and
filtering
â Can initiate an ADC sample sequence
â QEI
â Position integrator that tracks the encoder position
â Velocity capture using built-in timer
â The input frequency of the QEI inputs may be as high as 1/4 of the processor frequency (for
example, 12.5 MHz for a 50-MHz system)
â Interrupt generation on:
⢠Index pulse
⢠Velocity-timer expiration
⢠Direction change
⢠Quadrature error detection
â Power
â On-chip Low Drop-Out (LDO) voltage regulator, with programmable output user-adjustable
from 2.25 V to 2.75 V
â Hibernation module handles the power-up/down 3.3 V sequencing and control for the core
digital logic and analog circuits
â Low-power options on controller: Sleep and Deep-sleep modes
â Low-power options for peripherals: software controls shutdown of individual peripherals
â 3.3-V supply brown-out detection and reporting via interrupt or reset
â Flexible Reset Sources
â Power-on reset (POR)
â Reset pin assertion
