Full-duplex operation
Master and slave modes
Double-buffered operation with separate transmit and receive
registers
Four master mode frequencies (maximum = bus frequency ÷ 2)
Maximum slave mode frequency = bus frequency
Serial clock with programmable polarity and phase
Two separately enabled interrupts:
– SPRF (SPI receiver full)
– SPTE (SPI transmitter empty)
Mode fault error flag with CPU interrupt capability
Overflow error flag with CPU interrupt capability
Programmable wired-OR mode
I
I/O (input/output) port bit(s) software configurable with pullup
device(s) if configured as input port bit(s)
