Supports Motorola SPI frame format with a word size of 8/16 bits.
Texas Instruments SSI (Synchronous Serial Interface) frame format with a word
size of 4 bit to 16 bit.
Receive FIFO and transmit FIFO of 64 half-words each.
Serial clock rate master mode maximum 45 MHz.
Serial clock rate slave mode maximum 25 MHz.
Support for single data access DMA.
Full-duplex operation.
Supports up to three slaves.
Supports maskable interrupts.
Supports DMA transfers.
I
open-drain pins. This interface supports functions described in the I
specification for speeds up to 400 kHz. This includes multi-master operation
and allows powering off this device in a working system while leaving the I
bus functional.
