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
