1.5.15 Serial Peripheral Interface (SPI) module
The SPI modules provide a synchronous serial interface for communication between the PXD10 MCU and
external devices.
The SPI features the following:
• As many as two SPI modules
• Full duplex, synchronous transfers
• Master or slave operation
• Programmable master bit rates
• Programmable clock polarity and phase
• End-of-transmission interrupt flag
• Programmable transfer baud rate
• Programmable data frames from four to 16 bits
• As many as six chip select lines available, depending on package and pin multiplexing, enable 64
external devices to be selected using external muxing from a single SPI
• Eight clock and transfer attributes registers
• Chip select strobe available as alternate function on one of the chip select pins for deglitching
• FIFOs for buffering as many as four transfers on the transmit and receive side
• General purpose I/O functionality on pins when not used for SPI
• Queueing operation possible through use of eDMA
