Serial Peripheral Interface(SPI/SPIS)
The SPI interfaces enable full duplex synchronous communication between
devices. They support a three-wire (SCK, MISO, MOSI) bi-directional bus with
fast data transfers. The SPI Master can communicate with multiple slaves
using individual chip select signals for each of the slave devices attached to a
bus. Control of chip select signals is left to the application through use of GPIO
signals. SPI Master has double buffered I/O data. The SPI Slave includes
EasyDMA for data transfer directly to and from RAM allowing Slave data
transfers to occur while the CPU is IDLE.The SPI peripheral support SPI mode
0,1,2,and 3.The module have 3 SPI ports and they properties like following
table.
