LM3S6753 Datasheet, PDF (35/625 Pages) Texas Instruments – Stellaris LM3S6753 Microcontroller

Stellaris® LM3S6753 Microcontroller
• User-configurable interrupts
– Physical media manipulation
• Automatic MDI/MDI-X cross-over correction
• Register-programmable transmit amplitude
• Automatic polarity correction and 10BASE-T signal reception
– IEEE 1588 Precision Time Protocol - provides highly accurate time stamps for individual
packets
■ Analog Comparators
– Two independent integrated analog comparators
– Configurable for output to drive an output pin, generate an interrupt, or initiate an ADC sample
sequence
– Compare external pin input to external pin input or to internal programmable voltage reference
– Compare a test voltage against any one of these voltages
• An individual external reference voltage
• A shared single external reference voltage
• A shared internal reference voltage
■ PWM
– Three PWM generator blocks, each with one 16-bit counter, two PWM comparators, a PWM
signal generator, a dead-band generator, and an interrupt/ADC-trigger selector
– One fault input in hardware to promote low-latency shutdown
– One 16-bit counter
• Runs in Down or Up/Down mode
• Output frequency controlled by a 16-bit load value
• Load value updates can be synchronized
• Produces output signals at zero and load value
– Two PWM comparators
• Comparator value updates can be synchronized
• Produces output signals on match
– PWM generator
• Output PWM signal is constructed based on actions taken as a result of the counter and
PWM comparator output signals
