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
