'C24x Serial Peripheral Interface (SPI)
Serial Peripheral Interface (SPI)
All TMS320C24x devices include the four-pin serial peripheral interface (SPI) module, except the 'LF2402, 'LC2402 and 'C242. The SPI is a high speed synchronous serial I/O port that allows a variable length serial bit stream to be shifted into and out of the device at a programmable bit-transfer rate. The SPI normally is used for communications between the DSP controller and external peripherals or another processor. Typical applications include external I/O or peripheral expansion through devices such as shift registers, display drivers and D/A converters. Multi-device communications are supported by the master/slave operation of the SPI.

Features:

  • High speed, 1 to 16 bits programmable data stream (1-8 bits on F/C240)
  • Synchronous transmit/receive port
  • Master and Slave Operation
  • 3-Pin or 4-Pin operation option
  • Supports multiprocessor communications
  • SPI Clock phase and polarity control
