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 I2C
â Devices on the I2C bus can be designated as either a master or a slave
⢠Supports both sending and receiving data as either a master or a slave
⢠Supports simultaneous master and slave operation
â Four I2C modes
⢠Master transmit
⢠Master receive
⢠Slave transmit
⢠Slave receive
â Two transmission speeds: Standard (100 Kbps) and Fast (400 Kbps)
â Master and slave interrupt generation
⢠Master generates interrupts when a transmit or receive operation completes (or aborts
due to an error)
⢠Slave generates interrupts when data has been sent or requested by a master
â Master with arbitration and clock synchronization, multimaster support, and 7-bit addressing
mode
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
