24.2 Integration
This device includes two instantiations of McSPI: SPI0 and SPI1. The McSPI module is a general-purpose
receive/transmit master/slave controller that can interface with either up to four slave external devices or
one single external master. Figure 24-1 shows the example of a system with multiple external slave SPI
compatible devices and Figure 24-2 shows the example of a system with an external master.
