Architectural Overview
â Programmable interface operation for Freescale SPI, MICROWIRE, or Texas Instruments
synchronous serial interfaces
â Programmable data frame size from 4 to 16 bits
â Internal loopback test mode for diagnostic/debug testing
â Analog Comparators
â One integrated analog comparator
â Configurable for output to drive an output pin, generate an interrupt, or initiate an ADC sample
sequence
â Compare external pin input to external pin input or to internal programmable voltage reference
â 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
â PWM
â 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
â One fault input in hardware to promote low-latency shutdown
â 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
â Two PWM comparators
⢠Comparator value updates can be synchronized
⢠Produces output signals on match
â PWM generator
⢠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
