Peripheral SPI[edit | edit source]
The MCSPI module - in the DADA SOM - is a multichannel transmit/receive, controller/peripheral synchronous serial bus. Up to 5 (five) SPI ports are available in the DADA SOM.
Description[edit | edit source]
Each MCSPI module has the following 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 controller channels, or single channel in peripheral mode
- Controller 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
- Enable the addition of a programmable start-bit for MCSPI transfer per channel (start-bit mode)
- Supports start-bit write command, pause and break sequence
- Programmable shift operations (1-32 bits)
- Programmable timing control between chip select and external clock generation
