Stellaris® LM3S3749 Microcontroller
14 Synchronous Serial Interface (SSI)
The Stellaris^® microcontroller includes two Synchronous Serial Interface (SSI) modules. Each SSI
is a master or slave interface for synchronous serial communication with peripheral devices that
have either Freescale SPI, MICROWIRE, or Texas Instruments synchronous serial interfaces.
Each Stellaris SSI module has the following features:
■ Two SSI modules, each with the following features:
■ Master or slave operation
■ Support for Direct Memory Access (DMA)
■ Programmable clock bit rate and prescale
■ Separate transmit and receive FIFOs, 16 bits wide, 8 locations deep
■ Programmable interface operation for Freescale SPI, MICROWIRE, or Texas Instruments
synchronous serial interfaces
■ Programmable data frame size from 4 to 16 bits
■ Internal loopback test mode for diagnostic/debug testing
