Features and Overview

  • Supports Serial Peripheral Interconnect (SPI) Slave protocol
  • Supports protocol modes 0, 1, 2, and 3
  • Selectable input sources for MOSI, SCLK, and ~SS
  • Selectable output routing for MISO
  • Programmable interrupt on SPI done condition
  • SS may be firmware controlled

The SPIS User Module is a Serial Peripheral Interconnect Slave. It performs full duplex synchronous 8-bit data transfers. SCLK phase, SCLK polarity, and LSB First can be specified to accommodate most SPI protocols. The SPIS PSoC block has selectable routing for the input and output signals, and programmable interrupt driven control. Application Programming Interface (API) firmware provides a highlevel programming interface for either assembly or C application software.
