7.14 Multichannel Serial Peripheral Interface (MCSPI)
The MCSPI is a master/slave synchronous serial bus. There are four separate MCSPI modules (SPI1,
SPI2, SPI3, and SPI4) in the device. All these four modules support up to four external devices (four chip
selects) and are able to work as both master and slave.
The MCSPI modules include the following main features:
• Serial clock with programmable frequency, polarity, and phase for each channel
• Wide selection of SPI word lengths, ranging from 4 to 32 bits
• Up to four master channels, or single channel in slave mode
