There is serial peripheral interface (SPI 3) one channel in MC97F60128. The SPI 3 allows synchronous serial data
transfer between the external serial devices. It can do Full-duplex communication by 4-wire (MOSI3, MISO3, SCK3,
SS3), support master/slave mode, can select serial clock (SCK3) polarity, phase and whether LSB first data transfer or
MSB first data transfer.
