The MCSPI modules include the following main features:

• Serial clock with programmable frequency, polarity, and phase for each channel
• Wide selection of MCSPI word lengths, ranging from 4 to 32 bits
• Up to four master channels, or single channel in slave mode
• Single interrupt line for multiple interrupt source events
• Enable the addition of a programmable start-bit for MCSPI transfer per channel (start-bit mode)
• Supports start-bit write command
• Supports start-bit pause and break sequence
• Programmable shift operations (1-32 bits)
• Programmable timing control between chip select and external clock generation
• Built-in FIFO available for a single channel.
• Master multichannel mode:
  • Full duplex/half duplex
  • Transmit-only/receive-only/transmit-and-receive modes
  • Flexible input/output (I/O) port controls per channel
  • Programmable clock granularity
  • MCSPI configuration per channel. This means, clock definition, polarity enabling and word width
