Synchronous serial port (SSP)
SPEAr300 provides one synchronous serial port (SSP) block that offers a master or slave
interface for synchronous serial communication with slave or master peripherals
Main features:
● Maximum speed of 41.5 Mbps
● Master and slave mode capability
● Programmable clock bit rate and prescale
● Separate transmit and receive first-in, first-out memory buffers, 16 bits wide, 8 locations
deep
● Programmable choice of interface operation:
– SPI (Motorola)
– Microwire (National Semiconductor)
– TI synchronous serial
● Programmable data frame size from 4 to 16-bit.
● Independent masking of transmit FIFO, receive FIFO, and receive overrun interrupts
● DMA interface
