25.1.1 SPI main features
• Master or slave operation
• Full-duplex synchronous transfers on three lines
• Half-duplex synchronous transfer on two lines (with bidirectional data line)
• Simplex synchronous transfers on two lines (with unidirectional data line)
• 8-bit to 16-bit transfer frame format selection
• Multimaster mode capability
• 8 master mode baud rate prescalers up to f
PCLK
/2.
• Slave mode frequency up to f
PCLK
/2.
• NSS management by hardware or software for both master and slave: dynamic change
of master/slave operations
• Programmable clock polarity and phase
• Programmable data order with MSB-first or LSB-first shifting
• Dedicated transmission and reception flags with interrupt capability
• SPI bus busy status flag
• SPI Motorola support
• Hardware CRC feature for reliable communication:
– CRC value can be transmitted as last byte in Tx mode
– Automatic CRC error checking for last received byte
• Master mode fault, overrun flags with interrupt capability
• CRC Error flag
• 1-byte/word transmission and reception buffer with DMA capability: Tx and Rx requests
