Tiva^™ TM4C1232E6PM Microcontroller
14 Synchronous Serial Interface (SSI)
The TM4C1232E6PM microcontroller includes four Synchronous Serial Interface (SSI) modules.
Each SSI module 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.
The TM4C1232E6PM SSI modules have the following features:
■ Programmable interface operation for Freescale SPI, MICROWIRE, or Texas Instruments
synchronous serial interfaces
■ Master or slave operation
■ Programmable clock bit rate and prescaler
■ Separate transmit and receive FIFOs, each 16 bits wide and 8 locations deep
■ Programmable data frame size from 4 to 16 bits
■ Internal loopback test mode for diagnostic/debug testing
■ Standard FIFO-based interrupts and End-of-Transmission interrupt
■ Efficient transfers using Micro Direct Memory Access Controller (µDMA)
– Separate channels for transmit and receive
– Receive single request asserted when data is in the FIFO; burst request asserted when FIFO
contains 4 entries
– Transmit single request asserted when there is space in the FIFO; burst request asserted
when four or more entries are available to be written in the FIFO
