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:

•

Up to 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 4 to 16 bits

•

Up to 6 chip select lines available, depending on package and pin multiplexing, enable 64 external

devices to be selected using external muxing from a single SPI

•

8 clock and transfer attributes registers

•

Chip select strobe available as alternate function on one of the chip select pins for deglitching

•

FIFOs for buffering up to 4 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
