63 / 662 page  Peripheral Descriptions 5685X Overview, Rev. 4 Freescale Semiconductor 1-31 • Counters are preloadable • Counters can share available input pins • Separate prescaler for each counter • Each counter has capture and compare capability 1.12.6 Serial Peripheral Interface (SPI) The Serial Peripheral Interface (SPI) is an independent serial communications subsystem allowing full-duplex, synchronous, serial communication between the signal controller and peripheral devices, including other DSCs. Software can poll SPI status flags or SPI operation can be interrupt driven. This block contains four, 16-bit memory mapped registers for control parameters, status, and data transfer. SPI features include: • Full-duplex operation • Master and slave modes • Double-buffered operation with separate transmit and receive registers • Programmable length transmissions (2 to 16 bits) • Programmable transmit and receive shift order (MSB first or last bit transmitted) • Eight master mode frequencies (maximum = bus frequency/2 1) • Maximum slave mode frequency = bus frequency • Clock ground for reduced Radio Frequency (RF) interference • Serial clock with programmable polarity and phase • Two separately enabled interrupts — SPRF (SPI Receiver Full) — SPTE (SPI Transmitter Empty) • Mode fault error flag interrupt capability • Direct Memory Access (DMA) capability for both the transmitter and receiver • Wired OR mode functionality to enabling connection to multiple SPIs 1. This frequency may be further limited by the GPIO function. |
