LM3S6950 Microcontroller
⢠Output PWM signal is constructed based on actions taken as a result of the counter and
PWM comparator output signals
⢠Produces two independent PWM signals
â Dead-band generator
⢠Produces two PWM signals with programmable dead-band delays suitable for driving a
half-H bridge
⢠Can be bypassed, leaving input PWM signals unmodified
â Flexible output control block with PWM output enable of each PWM signal
⢠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
⢠Synchronization of timer/comparator updates across the PWM generator blocks
⢠Interrupt status summary of the PWM generator blocks
â QEI
â Hardware position integrator tracks the encoder position
â Velocity capture using built-in timer
â Interrupt generation on index pulse, velocity-timer expiration, direction change, and quadrature
error detection
â GPIOs
â 1-46 GPIOs, depending on configuration
â 5-V-tolerant input/outputs
â Programmable interrupt generation as either edge-triggered or level-sensitive
â Bit masking in both read and write operations through address lines
â Programmable control for GPIO pad configuration:
⢠Weak pull-up or pull-down resistors
⢠2-mA, 4-mA, and 8-mA pad drive
⢠Slew rate control for the 8-mA drive
⢠Open drain enables
⢠Digital input enables
