7.9.4 Serial Peripheral Interface (SPI) Module

The device includes the four-pin serial peripheral interface (SPI) module. Up to two SPI modules are available. The SPI is a high-speed, synchronous serial I/O port that allows a serial bit stream of programmed length (1 to 16 bits) to be shifted into and out of the device at a programmable bit-transfer rate. Normally, the SPI is used for communications between the MCU and external peripherals or another processor. Typical applications include external I/O or peripheral expansion through devices such as shift registers, display drivers, and ADCs. Multidevice communications are supported by the master/slave operation of the SPI.

The SPI module features include:

  • Four external pins:
    • SPISOMI: SPI slave-output/master-input pin
    • SPISIMO: SPI slave-input/master-output pin
    • SPISTE: SPI slave transmit-enable pin
    • SPICLK: SPI serial-clock pin

Note:

All four pins can be used as GPIO if the SPI module is not used.

  • Two operational modes: master and slave
    Baud rate: 125 different programmable rates.
    GUID-5B9E5347-D9EC-4FE9-946C-9A5D76753A23-low.gif
  • Data word length: 1 to 16 data bits
  • Four clocking schemes (controlled by clock polarity and clock phase bits) include:
    • Falling edge without phase delay: SPICLK active-high. SPI transmits data on the falling edge of the SPICLK signal and receives data on the rising edge of the SPICLK signal.
    • Falling edge with phase delay: SPICLK active-high. SPI transmits data one half-cycle ahead of the falling edge of the SPICLK signal and receives data on the falling edge of the SPICLK signal.
    • Rising edge without phase delay: SPICLK inactive-low. SPI transmits data on the rising edge of the SPICLK signal and receives data on the falling edge of the SPICLK signal.
    • Rising edge with phase delay: SPICLK inactive-low. SPI transmits data one half-cycle ahead of the rising edge of the SPICLK signal and receives data on the rising edge of the SPICLK signal.
  • Simultaneous receive and transmit operation (transmit function can be disabled in software)
  • Transmitter and receiver operations are accomplished through either interrupt-driven or polled algorithms.
  • Nine SPI module control registers: In control register frame beginning at address 7040h.
    Note:
    All registers in this module are 16-bit registers that are connected to Peripheral Frame 2. When a register is accessed, the register data is in the lower byte (7–0), and the upper byte (15–8) is read as zeros. Writing to the upper byte has no effect.

Enhanced feature:

  • 4-level transmit/receive FIFO
  • Delayed transmit control
  • Bidirectional 3 wire SPI mode support
  • Audio data receive support through SPISTE inversion

The SPI port operation is configured and controlled by the registers listed in Table 7-27 and Table 7-28.
